Minecraft Username: Nibirue Brief Description: When you use the fill lava command (using pyro+) then pour one of the buckets of lava, the lava bucket is emptied and all but one of the buckets in the stack disappears. Instructions: 1. Obtain 2+ buckets (I tested with a few buckets each time) that are empty, and stacked together. 2. While holding the buckets, use the /fill lava command to obtain lava. 3. Keeping the lava buckets stacked, pour out the lava once, somewhere. 4. Once you have done that, you will be left with a single empty bucket, and all other buckets disappear forever. How many times did you recreate this?: 4 times I believe. Once when it happened accidentally when I discovered, and 3 times to reproduce the bug. Each time I tried a few different amounts of buckets. I think I used up around 12 buckets in total in testing. Result: Every time I was left with a single empty bucket, and all other buckets in the stack were gone. Expected Result: One bucket would empty, leaving the bucket in a separate spot in my inventory, with the remaining lava buckets in my inventory OR the /fill lava command should not work on stacked empty buckets to prevent this issue. Evidence: I suggest recreating it yourself since it is pretty easy to test.
It's the way Minecraft works when you have stacks of buckets with liquid. You use all the buckets at once and all but one disappears. you can recreate this in singleplayer if you have a mod that lets you stack the buckets.
