I'm posting Bugs in here.
BUG 1: Items such as Holodices WILL get stuck in items such as the Group Gate.
BUG 2: Sometimes when trying to put 2 doors, One of the doors disappear.
BUG 3: Sometimes, Stacking will be incorrect. You should try to stack a Fan, A big purple fridge and any egg. The egg will be displayed incorrectly.
BUG 4: Wired will mess up sometimes. Let's say you take your wired from a room, and place it in another room. The wired taken from the room will sometimes have the same settings in the other room. And if you have e.g a Wooden Door, And you have another wooden door in the room, the wooden door will do what the effect wired was doing in the other room when the trigger is placed.
BUG 5: Some stickies which have (had) text placed in a other room from a other room, you put it in a wall, and it would say stuff you wrote earlier times ago.

Here's visual bugs.. Hope you fix them (except the fifth one)
