Can you please send me a screenshot of the issue?
sorry for the long reply, heres the issue
Uh I got your issue! You need to place the Floors file in the A2 (Ground) slot, the Walls file in the A4(Walls) slot and all the other stuff in a slot from the Tileset B to the Tileset E!Let me know it that one helped ;)
Did you manage to solve the issue secondhr?here you have an explanation on how each tileset slot works, if that can helps ;)
