Again, not sure if this is due to rotation or what, but this dungeon looked like this screenshot before I tried it in the player. : P
thank you for the info and the links! someone else seemed to have the same issue and suspected the same thing as you earlier. i have a hunch it is due to rotation- that would make sense. i'm terribly sorry, this is such a tragic bug. i'm working on a fix right now, and i'll upload it tonight. hopefully that will be the end of the tile garbling bugs.
