[MCPE-48421] Items smelted in a furnace may not stack or be used in composters etc

The composter no longer accepts baked potatos after 1.12 update on both the xbox one and windows 10 versions. I found the issue because I have a machine which is a chest that dumps raw potatos in to ovens and then into composters and drops bone meal into a chest. I noticed it was not running. The hoppers were full above the composters and the composter were not accepting baked potatos. So I made a new composter and put in raw potatoes and it turned them in to bone meal. I then tried to put in baked and it will not take them. Please don't tell me this is a new feature. we need the bone meal for our sugar cane machine.

I did some testing and it appears this only happens if the potato was smelted in a furnace. If you take baked potatoes from the creative inventory, the composter will compost them.

Dried kelp also has the same issue.

This seems like the same furnace issue as in MCPE-47907 (stone) and MCPE-48342 (coal).

Updating the ticket and making it a general issue for items that are smelted through a furnace not stacking or being usable with a composter etc.

I would like to add that I've noticed this behavior in Player-Inventory as well as in chests etc.

I.E. Smelting cobblestone in a furnace to create stone wont allow said stone to be stacked with stone mined with silk touch. Creating coal from wood in a furnace will not allow this coal to be stacked with coal found in villager chests/mined from ores.

The same occures when you try stacking leaves harvested with shears with leaves you got using an axe with silk touch.

This becomes a major issue when it comes to Inventory Management.

I'm pretty sure that if items won't stack in a slot somewhere, they won't stack in any slot anywhere.

As a workaround for your inventory management problem, try placing the leaves and mining them again, all with the same tool so they all have the same internal data. I think they should stack then.

Getting leaves, stone or any block with silk touch and getting the same type of block some other way also doesn´t stack

Nick Fagerness 2019-09-13T01:18:29Z

Can somebody tell me how this issue relates to my issue of my stone mason won't accept my smelted stone?

Auldrick 2019-09-13T02:06:28Z

@unknown: Blocks and items are identified internally by an ID number. Some of them also have an additional Data Value number that distinguishes blocks and items that have the same behavior but different appearance. If you use commands, you've probably used the data parameter to specify a color or material type for a block or item, for instance. Those are examples of the Data Value.

The bug reported here occurs when a block is broken, which converts it to an item, or when an item is transformed in some way, such as by a furnace. In the process, the data value gets corrupted, and the result is that the item looks like a different kind of item to the game, even if it's rendered the same way on the screen. Because the game thinks they're different kinds of items, it can't combine them into a stack.

Similarly, your stone mason won't accept your smelted stone because it has a corrupted data value. The stone mason therefore doesn't think you're trying to give it what it wants, so it refuses it.

Today I found that in my old world newly smelted stone doesn't stack with my existing smelted stone I created on older versions. Also I can't trade the "new" stone.

Did anyone find a workaround for this that we could use until it's fixed?

Auldrick 2019-10-16T22:59:14Z

Try this: Take a piece from one batch and place it. Then mine it again and see if it will stack with the other batch. If it doesn't work in one direction, try the opposite one.

I use this method often on leaves, but I think it should work for anything that should stack but won't.

If you smelt coal ore into coal, it does not stack, and there is no way to fix it but making it into a block and decrafting it back into 9 coal.

Vivi Larsen 2019-11-02T21:34:49Z

That's not an fix, Auldrick - it's barely a workaround. After the last update the trader refuses my stones also. I have some chests completely filled with stone from 1.12. Time for Mojang to make fixes to solve issues that reappear with every update - not suggest workaarounds that is sisyphuswork for us players.

Kenny Harris 2019-11-02T22:09:36Z

I got around the issue with 18 full chest of baked potatoes by creating a new stack of baked potatoes then spread the stack across an empty chest slots so each has one or more in each slot. Fill inventory with pre 1.13 items and transfer to chest where you just spread the new items. They should be converted to the new 1.13 version item. Took less than an hour to convert 18 chest and compost them.. hope this helps

Vivi Larsen 2019-11-02T23:53:02Z

Have tried your solution, Kenny. Sadly it didn't work on my old stone. 😞

Nathan Row 2019-11-03T00:01:58Z

This does not seem to be fixed at all

Auldrick 2019-11-03T15:45:53Z

@unknown: I didn't intend it to be a fix. I don't fix things, I'm just a bug tracker moderator, an ordinary community member trying to help people affected by this bug. So let's try to avoid snarky soap box rhetoric here; it's not helpful. So are you saying a Wandering Trader is refusing to accept stone that you smelted in 1.13? What is the trade you're trying to make?

@unknown: Unfortunately, fixing the bug doesn't fix the items that were already corrupted by it. Any items you smelt from now on should be correct, but they still won't stack with previously damaged items. The workarounds being suggested are meant to be things you can try to repair the damaged items in your inventory. If you think the furnace is still corrupting items as it smelts them, please give specific details so we can check whether there's still something that isn't working right. Be sure to mention what you smelted and why you think the output was incorrect.

Nathan Row 2019-11-03T16:09:29Z

Thank you Auldrick, I will try isolating the pre-1.13 items that don't stack together and see if it happens at all with new ones. Had been having ongoing issues with items obtained different ways not stacking properly (if obtained with silk touch vs. furnace vs. picked up from explosion, etc.). Hoping it is fixed, appreciate your help

Auldrick 2019-11-03T17:01:47Z

Note: Silk touched leaves not stacking with leaves obtained using shears is a different bug, MCPE-41408. That bug has also been fixed. If you find there are still problems with new leaves obtained using a silk touch tool, please comment there.

Also, MCPE-54617 describes the issue of previously damaged items that won't stack with new items since the fix. It refers to all kinds of corrupted items: stone, leaves, food, flowers, etc. Mojang may not be able to fix those items in every case, but if there's enough interest from the community, they should be able to fix most of them with special patch code in a future release. So I would suggest upvoting MCPE-54617 if you have a lot of damaged items and don't mind waiting a while to get them fixed. And if the kind of items you want repaired hasn't already be mentioned, be sure to add it in a comment.
