Hi! New user here. I'm experimenting with custom DLC today and I can get everything working fine except for map themes. I downloaded different themes and placed them in the "MapThemes" subfolder. These themes are listed in the CS menu and I can select them when loading a map, but for some reason the themes don't load in sandbox play. I tried using the Environment Changer mod, but it made no difference. Here's the weird part: I can load the themes in the theme editor and they show up fine. I've also tried making changes and saving them under a new name. But no matter what I do, the themes won't load in sandbox play. What am I doing wrong?
