I haven't mate, do you think I should? I always feel like the SI forums are a bit of a waste of time for stuff like this. I know they're the official forums, but it's so big and cluttered things get lost very easily.
I'm gutted to be honest. I was really enjoying the save. I've considered buying the official in-game editor and manually upgrading them, but it'd feel a bit cheap, even if I took money from the club's balance to offset it.
I dunno about it really mate, I guess if it's a bug you could get some kinda response from a mod or dev and see if it's really a bug and can get fixed. Regarding the in-game editor, well see if you can find something that sticks, if not you can come back to this that way.
