Another inventory related bug, easy to reproduce:
Shift click on anything after opening an inventory of something (like tannery or dryer)
If the thing you wanna place there only can go into a not full stack only an error message occures that the inventory is full. instead of combining the half stack with the wanna placed item. Sorry for my lack of english words for it. and hope you understand what I mean.
It used to move just the right ammount from your inventory to the “machines” inventory to fill up that given stack. now it is broken after patch #33.
