Thanks for your mods!
I've had errors after installing your mods "[Vanilla + DLC] Diseases Expanded" and this one. Strangely enough, this error occurs when I try to load/reload a save from within the launched game. Yet I can load a save from the main menu.
This is the log for this mod:

I'll publish the log for the "[Vanilla + DLC] Diseases Expanded" in that mod "discussions".
I play with lots of mods. If you want to try and reproduce this issue you can use my modlist https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2940075329 .

After uninstalling these two mods the error has gone.
