On BB+, for some reason, the trees doesn't have billboarding just like the other objects
Edit: Oh, and in some floors (seeds), sometimes, the character modifier is inaccurate, sometimes it shows duplicated items (like 2 1st prizes for instance) or just doesn't have the character inside the list (mostly Principal on F3)
Another edit: If using the Environment option and selecting a table, the table will always move to the left/right (based on it's rotation relative to the player's pos)
You cannot select tiles by clicking on the ground, ONLY walls (you can't select an open tile)
