Brief Description:
In skyblock, stack of polar bears don't drop the amount of items multiplied by the amount of mobs in that stack when they fall to death.

Instructions:
Drop a few polar bear stacks to their death and see only drops of 1 mob
(NOTE: I guess this may be a problem with all passive mobs, not polar bears only, I haven't gotten to try any other passive mob yet but i suggest you check some other mobs as well)

How many times did you recreate this?:
2

Result:
Polar bear stack dropped drops of only 1 mob (i literally got 2 fish from a stack of 500, 2 times in a row)

Expected Result:
Polar bear stack drops loot multiplied by the amount of mobs in that stack (in the case that happened to me, i was supposed to get 1000 fish instead of only 2)

Evidence:
I can't provide any evidence at the moment, just try this in game and you'll see :)
