In advanced mode (i.e. via hitting TAB):
Since the last patch, can’t seem to be able to reposition, rotate, extrude, or pretty much anything else that makes use of click-and-drag behavior, while having the log window open. As soon the log window is closed, it starts working again.
Should be pretty easy to reproduce, just place any entity in the world and try to change its position/rotation with the handles in the game (not in the entity tree). Equally try to extrude any voxel mesh.
