So i found out that the patch ruins raul's sidequest so i tried removing the patch to try talking to ranger andy again, thing is when i was about to load it i got the DLC prompt - i knew if i hit load something bad would happen, so i reapplied the patch and the prompt went away.

this is a playthrough i made with the patch by the way.

food for thought.

So your telling me that when you got this patch, it fixed the DLC error and game saves?

well technically there was never anything broken in the first place, so it didn't fix anything

It did not fix anything, but when you applied the patch the DLC error went away, right?

yep, don't know if it would work for anyone else since i never tried to load the files when i took out the patch in the first place so nothing probably got corrupted.
