3 years ago After some searching through this problem, which has apparently existed for awhile, I've found the solution to this issue. It needs to probably be baked in to the game. Simply disable "Graphics Facelift Mode" while playing Tyrants of the Moonsea. The facelift version of the tileset has some incompatibilities with the module version.
There are some major flaws in the Elventree tileset, such as textures that overhang chasms and buildings placed on chasms.
