[MCPE-14136] Items Duplicating in hot-bar After Use

Realms Alpha Build 2 and 0.14.2
While in a realm, items being used in hand are being duplicated over an item in the hot-bar menu.

IE:
1) Walking around with a map in hand
2) Switch to a sword to kill a zombie
3) the map turned into a sword
4) Now I have two swords

Another IE:
1) Mining
2) Pull out pick ax, start mining
3) A random item in the hot bar turns into a pick ax
4) After mining for a while, I now have 6 pick axes in my inventory when I started with one. Random items- bread, axes, stacks of iron ore, wood can potentially turn into the item being used.

I have had all sorts of items get duplicated, including stacks of food and plants.

It is random, and difficult to reproduce, but it happens once or so every 5-10 minutes.

EDIT:
I can now accurately replicate this duplication process. Here is the procedure:

1) Fill one item in each of the hot-bar spaces.
2) Take a pick ax, and place it into one of the hot-bar spaces.
3) Go into the inventory, and change the location of the pickax in the hot-bar with another hot-bar item (effectively just swapping places).
4) Immediately use the pick ax, and it will duplicate the pick ax with the item that you swapped locations with in step 3.

This also happened to me with different items such as buckets (even if filled with water or lava), swords and other equipments, foods and even plants. Like almost everything I had

Can confirm on Nvidia Shield K1 running Android 6.0 MM

Blu 2016-04-22T07:12:57Z

Confirmed on Samsung Galaxy J7 running on Android 5.1.1 and that this can indeed happen with any item.

Toon Vanoeteren 2016-04-22T10:44:50Z

I'll confirm aswell, Samsung Galaxy S4, running 5.0.1, issue is persisting

Samgsung 10.1 HD, Windows 10 confirmed as well.

Also, an item at the end of your inventory list will be permanently lost when this bug occurs.

Anthony Flower 2016-05-07T08:25:02Z

Seeing this on 0.14.2 on iOS too, just on multiplayer and just the guest, never the host.

ScW77 2016-05-08T10:40:22Z

Happening here too, very upsetting when all mined diamonds disappear.
Happens on iPad and Lenevo tablets.

Jonathan Osborne 2016-05-09T15:40:46Z

Happens in multiplayer. Not on the host. To duplicate place 3 different items in the first three quick inventory buttons at the bottom. Use item 3. It will replace 1 or 2 with item 3 and erase the previous item

Sergey Mitilino
When Minecraft Windows 10 Edition is a server and Pocket Edition for iOS is a client some items like maps, swords, bows disappear or double randomly in Minecraft client inventory on Pocket Edition for iOS.

@Sergey Mitilino Please create a new ticket for any separate bugs, rather than posting irrelevant comments on other tickets.

This issue is Invalid, as it affects Realms Beta Testing, which has ended. If this issue still affects 0.14.2, please comment down below.

Icode 2016-05-16T22:45:13Z

What do you mean "still affects 0.14.2"? Is there a patch to this version?

kaleb418 2016-05-16T22:54:11Z

@James M To return to the 0.14.2 update, uninstall the app and reinstall it. This won't erase your worlds unless you have other software cleaning your device.

Icode 2016-05-16T22:58:08Z

Sorry...

To clarify: You asked if it "STILL affects 0.14.2" – why would it ever stop affecting 0.14.2 unless there was an updated, which there is not? Or is there? FYI: I just a public user who installed 0.14.2 from the app store. Yes, this issue exists in the released version: 0.14.2

kaleb418 2016-05-16T23:02:37Z

@James M Sorry, this was my mistake. I didn't see that you already had '0.14.2' in the affects version area.

kaleb418 2016-05-16T23:02:58Z

Reopening...

Icode 2016-05-16T23:09:00Z

No worries. I'm, a little new to this and wasn't sure if I missed something. 🙂

Elkniwt 2016-05-19T13:10:55Z

For the record, I still see this in 0.14.3. I've only ever seen this as a client, not the host. The host never seems to see the bug (as others have mentioned). It began happening with 0.14.2, we used to play all the time on 0.14.1 with no issues. Host device is Asus TF201, clients seeing the issue are Samsung Galaxy S5, iPod Touch 4th gen, and iPhone 4s.

Icode 2016-05-19T18:01:19Z

Shouldn't we close: https://bugs.mojang.com/browse/MCPE-14161
and https://bugs.mojang.com/browse/MCPE-14371

kaleb418 2016-05-19T20:08:02Z

Does this still affect 0.14.3? If so, please respond.

Klaus 2016-05-19T20:23:17Z

Yes, this bug also affects 0.14.3, tested on iOS and android. Instead of constantly closing and reopening this issue formally, I suggest some developers have a look at it. ^^

Klaus 2016-05-25T22:07:30Z

I have to revise my last comment. Since 0.14.3 is out, I experienced this bug only once. The server was an android phone and the client was iOS 9. Both were already updated to 0.14.3. Since then I was unable to duplicate items and therefore it seems to me that the bug is almost gone. Or it is finally gone but the android phone was not properly updated when we tested this. unlike my mate said. :X

Elkniwt 2016-05-26T15:53:32Z

I have to agree with Klaus. I thought my 0.14.3 testing was thorough, but I now have evidence that the client I was using was still on 0.14.2 while the server was upgraded to 0.14.3 (is this even possible?). When I was eventually notified that I had an update on the client device, I was surprised when it didn't bump to 0.14.4, so I must have been back on an older version. I'll have to proceed with thorough "testing" later tonight, but if I don't come back here, the bug is gone for me.

Elkniwt 2016-05-31T19:47:49Z

Yep. Plenty of "testing" done. This bug seems gone in 0.14.3.

kaleb418 2016-05-31T20:31:23Z

Ok. Resolving as Fixed. Please comment below if anyone still experiences this issue.

Nate 2017-08-26T09:43:57Z

I made a sick ass island cave base that's all redstone. But when i choose an item from the inventory for example like a sword it duplicates the sword 6 more times #fixit

Joseph Maryanski 2018-05-15T14:30:55Z

Seriously guys, get your stuff together over there. This is a HUGE issue!
It destroys multiplayer. It has been ongoing since the update and
apparently little to nothing has been done about it. Why don't you read
down the comment section in the app store. Most people don't know about
reporting bugs so they leave their headaches there and every other
complaint (probably more) is about this bug! Fix it already.
