Thanks alot :)
Also, you mean Tileset1 since Tileset0 is the default one lol :p
Well I've putted 2 full houses without removing the tiles that repeat, but I still have space there for at least another building and quite some nature tiles.
Also yeah it might be true that it can store only 2 houses, but depend of how you insert them.
If you insert them yourself try to avoid repeatable tiles or tiles you can use X/Y flips.
And in tileset 0(Default) I have only the PC that is both Pc and mart, everything else is nature.
Hope this answered your question, if not feel free to VM me again :>
