Smelting a wet sponge when there's more than one empty bucket in the fuel slot of furnaces will destroy all the buckets in favor of a single water bucket

I don’t understand how this can be seriously flagged as Works As Intended.

You’re introducing a behavior which cannot possibly be forseen by players. Consider this:

1. Fill every slot in your inventory with cobblestone but one
2. In that empy slot put a stack of empty buckets
3. Start picking up lava or water

What happens is this: you start dropping lava/water buckets because they can’t fit in the inventory. You don’t destroy 15 buckets to get 1 full bucket.

So following this logic, furnace should drop 15 buckets to the ground and leave 1 water bucket in fuel slot.

This is not a discussion platform, it's a bugtracker. Please use it accordingly.

I'll make an exception this ONE time and answer your question here: The problem is not that the buckets disappear, the problem is that you can put more than one in the fuel slot in the first place. This will be solved differently, but the behavior that you describe is WAI.

Thx for resolving.
We need a solution for auto-filling buckets. 😉

Reopen this bug and retitle it "Furnaces allow more than 1 empty bucket to be placed in the fuel slot." Or mark it as duplicate to some other bug that already tracks the issue from that perspective. But don't pretend that it's intended behavior that placing a stack of buckets in the fuel slot destroys all but one of them when you yourself just said that bucket destruction is not intended.

I note this bug has been fixed in 14w26a, in the manner Searge described.
