Not solved yet - 0.12.0.0 - 3 Treasure Chest bugs

[Sebt]

1. Enemy can't destroy a tile of your room if there is a Treasure Chest placed;
2. Treasure Chests that are placed in a room cannot be opened until a room beneath it is sold;
2. Treasure Chests are always the last task to open (as well as items it contains to gather) before any old or new added during the game. Treasure chests opening has the lowest priority and that's why they haven't been opened there yet;
3. If you sell a room tile that's beneath the Treasure Chest than what's inside that chest will teleport one tile away from it, however chest is still closed.

Check those images:

I also spotted that opening chests are the last thing to take care of, even items that were put there are lost to be taken by Imp.

Interesting! Added to the list of Bugs/Issues & Crashes

I corrected point 2, because I found the cause.

Hmm this is really weird, because how can you own a room beneath a treasure chest? This level is created inside the editor right? That you set yourself as an owner to the room the chest is on.

These chests were placed on Impanzee Room first, that I later claimed the room with them inside. Than enemies appeared, destroyed this room, but they couldn't touch Impanzee Room tiles on which these treasure chests in the picture were placed.
