I would agree with a few people here. there are some serious gameplay-halting bugs, like the item vanishing bug mentioned. its easy to replace in a solo world by switching to creative, but, a) that ruins the fun, and b) isnt always replaced (usually isnt) in multiplayer settings, which can cause serious setbacks. the animal pathing is also still very janky, for example the gazelles running away then switching to run towards you, plus cave ins causing serious eruptions of stone in some cases, or causing the mantle to fall.
more content would mean more bugs, potentially some worse than what already is present, and you could get buried in that pretty quickly, so i think dejank should definitely be at least high up on the priority list.
