I been having problems with texture loss, and this is after taking a long time with working with textures only to lose it all, then having to begin working the same, only lose it all again, its very annoying, so for now there is only one texture used to fill map.
You may load up ZOMBIE LEGEND and find whole map surface has turned a total white colour, so having to add in your own textures can only fix this problem.

Also when I first subscribed to dotd mod, then after clicking on textures (showing in purple) then I get game crash, so I copied and pasted mod into mods folders via Goh directory and this fixed the issue while texture names showing right colour rather than purple colour.
