After some more testings, I can confirm that even on a 1.21.5 SERVER, the stacked items continue to behave weirdly as listed previously. Also, referring to AKAN5’s video, he offhands the stacked item first then puts in back in his inventory. There are some issues with this as this only works if you unoffhand it in a main inventory slot. If you open your inventory and then unoffhand it any slot, it will put a single from the stack in the slot you unoffhanded it and would remove 1 from the stack which would still end up staying in your inventory. With that saying, I humbly request that this bug report is put off of the Resolved status, as the problem is still not yet solved, because the normal behaviors are bugged. I’ll list them again just incase:
Doesn’t show item count
Shift clicking said stacked item will now fill up the inventory as if it had dropped 64 singles of the item instead of a full stack
Dropping a full stack and picking it back up also does the same thing as this ^^^
You can move a full stack of a unstackable item if its in a container of some sort and you press an inventory slot hotkey while hovering over said item.
You can also hover over said item and press the offhand key which still puts a full stack in your offhand as normal.
Items with less stack capacity (e.g. books, signs, ender pearls that only stack to 16) show the item count but only as 16 and then the behaviour is once again the same as the other items.
Humii
