Update did something to my save file.

Turned my game on for the first time in like 2 maybe 3 months. Saw there was the update and my old save files say “Save File is from a different version. This may cause the game to crash.”

Loaded in and it didn’t crash, but all the things I renamed were either reverted back to their original name or was just a blank text box. Also with the map update it gave one of my vassals all the new territory so he is currently sitting at 646/6 holdings.

Any ideas on how to fix this other than just starting a whole new game file. Really don’t want to do this since I’m at year 950 AD already.
