I have close to 400hrs on the game and I have never had any issues before.
However, since the Landfall update I have come across a myriad of them, notably huge performance issues and more recently, my progress not being saved.
I left the game for a couple of months and came back to playing it yesterday. However, when I logged on again today, I noticed that nothing I had done had saved as I had spawned back in the same safehouse that I was in when I returned to the game. I hadn’t done a lot, but I had fast travelled between safehouses. I tried this again numerous times today and each time I enter back into the game I respawn at the same safehouse (Averholm Manor).
Another noticable thing is that every time I boot up the game I am greeted by the End User Lisence Agreement message as well at the Crash Report message. For this reason I can only conclude that absolutely nothing I do will be saved.
This problem is only for Generation Zero, all my other games are fine. Also, I am on PC.
Edit - should also probably mention that I have tried a full reinstall to no effect.
