Alright, we've also fixed that first crash while trading, will be fixed in the upcoming patch
In terms of the second crash, please note that the stuck games may still not be recoverable. The problem occurred when you had left the game, and the crashes are just a symptom of the state that it put the game in. The fix will prevent the root issue from happening again. You may still be able to salvage the stuck games by simming past the date or trying to skip it (I was able to recover some of my test games), but it's not guaranteed.
