[Created people do not appear in game]

Fair warning if you import from fm21, looks like the boolean value of "Has Work Permit" got flipped. So you'll need to toggle everyone who needs a work permit OFF to get them to have a non-expired work permit.

It certainly hasn't fixed files created under the previously buggy version. I'm trying a couple other things now.

I'm not sure if it's relevant or might help you track down the bug but I noticed when I tried to add player partnerships (under the team -> STaff and players) I got the following weirdness.

Search for player

Search finds player just fine. But instead of putting the player's name under "Player 1" it instead shows this rather bizarre error *NO RECORD FOUND FOR 2002042257 which is the correct ID for the searched for player. Seems like some query is borked somewhere and that may be causing a cascade of problems.
