Save data was created with a newer version of the game
Ok so I would like to start this off with:
Yes I have looked at other threads
No I don't have a single mod all that's been added to the game is what the DLC has given me.
Recently upgraded to a new computer and figured all would be ok because cloud save is a thing. Went to go back to one of my old saves because I finally got trespasser, went to click on the save and was greeted by the lovely message "This save data was created with a newer version of the game. Please download the latest patch and try again."
Well ok I thought time to google, did some reading and the only time I saw people with this problem they were using mods. I checked my version of the game through the package file and all it has in there is:
Name patch
Authoritative
Version 12
Ok I thought to myself, 90% sure I have the right version in there what now?
Haven't seen anyone else with this problem who didn't have mods so at this point I'm not sure what to do, I just want to be able to do trespasser on my old saves so my inquisitors can finally have their happy endings.
@TatsuDragneel; Ok, so you say you aren't using any mods. But that error message indicates that the save you're trying to use was made while you had at least one installed. (Or possibly a patch that is now not installed.)
In any case, if that's all that's wrong the fix is easy:
Open the file(s) "package.mft" with any ASCII text editor and increment the version number by 1. Rinse-Repeat until your save loads.
[NOTE: It may be hard to tell which of the (potentially) many "package.mft" files you'll need to adjust, but take things slow and you'll figure it out.]
