GS12 is still in first beta, so it is expected to have issues with custom databases. Eugene will check the savegames with custom databases and fix for next version

#35667 trevsinclair85 : It works!! Did what 'feelingverycold' said, started a new game and before started unticked my data editor files. It seems this issue is to do with a database that has been edited before.
Thanks for help everyone!!
