Bug/Issue Game Crashes after Witch Event

After going to sleep this is what is happening. Adding a check if(object.ContainsKeys(x)) would prevent this from throwing an exception.

Message: An item with the same key has already been added.
InnerException:

Got the fix. I had to open the save file, find the coop that she was flying over, in this case it was my Big Coop, and remove it from the save XML file, MAKE A BACKUP FIRST!!!! After loading the game, after the removal, she flies over my slim hutch and the game saves just fine. Go modify the save file once again and add back your big coop (from your backup file location under <Buildings>). Reload the game once again and you should be good to go. Because the witch event completed successful there is no more crash issue.
