Ive already made a thread about it way back, but I cant find it and I guess it was forgotten.
Ive thought this bug might have been caused by setting "Dungeon textures" to "Climate" but after more testing, even with "Classic" setting, this issue still persists.
It would be cool if the textures actually matched, it would help navigation a bit and that is something we really need.
Thanks for considering that
