So i tried using robb stark on the westeros map with scenario turned on. For some reason it crashed and i lost about 30 gb of disk space on my pc. I tried once more and lost 30 more gb of space. Found out that the game for some reason made a 30 gb initial save file when the game crashed. idk whether this is fixable(likely not). But i mostly made the post so if people experience the same they can come here.

Fix if anyone should encounter this aswell is to delete the modded saves. They should be in this folder:

Documents/my games/Sid Meier's Civilization 5/ModdedSaves/single/auto
