Okay, something really weird happened with the database. Some of the managers moved and all of Jabba's players got removed, but then a few of Wee3Men's players moved over to his team. NFI how it happened because I didn't touch the editor. I'll have to go through and check each team again.
hmmm maybe they all decided to retire or maybe my team is just not appealling solution: if it is only old players going mia just change their age.
Mate try this When you're loading up your custom database, you would 'un-click' "add players to playable teams" (this is the screen after the one where you choose which countries you want to have running as playable or view-only).
FML. Sucks having to re-enter half the teams. @Zohaib: Just found that you have got Vincent Kompany but Gazza already picked him. Eden Hazard picked by Smousey. NFI how I didn't pick up on it the first time.
