I cannot save my games after the save file becomes around 70mb. And file sizes are so inconsistent. My 20 day save file is around 70mb and I cannot be able to save, while in another campaign which is 1400 days in, save file is under 60mb and I can save that one. Both campaigns are using the same mods. Is there a way to fix this? Editing, decreasing save file for example, I don't know?
