It would be very helpful if you could provide us with defective save games. The best way to do this is to put the save game from the user folder (e.g. C:\Users\User\Documents\My Games\Cattle And Crops\Profiles\User\Save\slot-2) in a .ZIP file and upload it to dropbox or Google Drive.
Afterwards you write a post and share the link.
Please also give us a short description about what happened at the time of saving, like for example that the worker was cultivating field 1 and the Dammann was filled.
Please also tell us what kind of error happens (Game crashes? AI Helper is confused? …).
Thanks a lot!
