Did you have a save from the old version? If so, then there was the same problem. Everything was solved by the fact that I'm playing on version 8.1, but I downloaded the save from version 8.0. I just need to reset things and save events. In the save download menu, next to the start "selected" button, select the day you want to start from. However, in this case, all items from the inventory and on the base disappear. And in general, the database returns to its original form, with the exception of some garbage. Well, or start a new game. But it helped me, because about 5 events happened on the same day. I'm sorry for the mistakes, I used a translator.
