1/ When you have any stackable item in your hand/inventory of any kind, you cannot right click on the stack to split it into two piles.
2/ Also cannot stack planks into piles of 20 (unless you put the cutting piece you are working on into a car or backpack).
3/ Players cannot swap piles between 2 sources.
4/ Crafted fireplaces when put on the ground are unable to be lit (or once in about 50-75 instances).
1/ put any stackable amount of objects in inventory or hand and try to right click. it doesn't work
2/ try putting 2 stacks of planks together say 7 and 8 each, and try to combine them into a stack of 15. goes to 10 per pile, yet you can cut them to 20 per pile (?)
3/ if a stack of 20 planks is in your backpack, try to swap for a smaller pile of planks, cannot do.
4/ craft a fireplace, place it on ground and try to light it.
all of these actions could be done before the update but not since
