I decided to write this report after I did some testing on a bug I saw quite a few people reporting on discord, and came to the conclusion it is indeed a bad bug. What happens is when you break a chest full of crops, and it happens to be within the same chunk as a PF hopper, only when the chest is broken with auto-pickup, or /auto, and with a full inventory, the crops within the chest will be picked up by a random PF hopper inside that chunk. And once that hopper is full, the rest of the crops disappear completely. I've tested many different ways to get this to happen and the only conditions for it to work at; Chest with more than 5 stacks of crops, broken with auto-pickup enabled, in the same chunk as a PF hopper, with a full inventory. The bug is the same on both Potato and Carrot, and does not apply with anything that is not a crop, or with auto-pickup disabled.
