Playing solo in a Ordo Xenos mission (flying infant) with a 82 level Psyker. Midway into mission I get a CoreTech2 error with the following message:
fatal error at ..\..\src\gamelogic\helpers\idmanager.cpp(157): Not enough free ID! UserID: 0
Reloading the game and replaying the mission it crashes around same area in the mission it had before with the same error message.
