Hi, I've had this problem many times before: At some point during the game (any scenario), I realize that all the other civilizations have defaulted to their vanilla names and titles. On top of that, all scenario parameters are also reset to their default values, the date is recalculated to reflect the number of passed turns, depending on year/turn increment in case it was non-standard in the scenario. As you can imagine, this is extremely annoying, especially when the last save while everything was still ok has been created hours ago. Loading a valid save helps, but of course the progress is lost. Has anybody experienced this? Is the cause known? Can I prevent this somehow or fix an already messed up save file?
