So, some textures seem to be messed up in my project for seemingly no reason.
I've got Darkbase alongside some other texture sets, and all of the Darkbase side textures are missing in-game. However, the odd thing is that there is one particular texture from a completely different set of textures missing. I use Wadmerge, so all the textures are divided into just two segments, flats and sides.
I've got no clue what to do about this, as rebuilding the TEXTUREx and PNAME lumps don't do anything. It was working flawlessly yesterday, and I can't for the life of me figure out what could be causing this.
