So I recruited two Sorcerer Hero, and at the moment the turn ended, they vanished. I repeated this twice, and only on the third turn did they still exist. Haven't seen this with any other faction, only the Cabal.

Only difference is the last turn it was a Metal lore and a Tzeenyweentchy lore, rather than two Tzeentch.

Low priority issue, TBH, just saying. Will update if I can find a cause. (Maybe the Cabals corrupting local mages is working on our own mages somehow and killing them?)
