Stardew keeps restarting

[john doe]

after using the farmfoundry program to move somethings around in my moded farm, I'm unable to open the save back up. everything i would load the save it would bring me back to the title menu. Smapi would show this after every restart.

[game] deserializeTask failed with an exception.
