[2020] Is there anyway to relock the maps?

Originally posted by Novakiin: I was wondering if there was a way to relock the maps. I let my father use my steam account to try the game out and he enjoyed it, but when he bought the game he still had my map unlocks and would like to try and progress through the game noramaly instead of having everything unlocked.

Delete your Account.zxuser and Account_backup.zxuser file in the path Documents/My Games/They are Billions and your Survival maps will be again locked.
