I editied the files to make a cat preggos and this happened and i was drawing the whole clan as well please help
This happened to me earlier. Sadly i had to go into the pregnancy.json and delete whatever was in there only leaving {} .
And i had to go back in time and hopefully pray to role a cat who was expecting kits, save the game, and going back into the pregnancy file and changing the ID's of the cats. Hope this helps.
