Game crashing when resource gets full

Disabling mods does not undo what effects they have already had on a save game file.

Do you get this in a galaxy that's never had any mods used in it?  

I can understand that! But I can't report a crashing save when mods are involved.

I think your goal here is to rescue that save, would that be right? If so you might try the User Mods forum, as they have more experience in what can be done by editing save files.

Good luck with that!
