There appears to be a minor bug in the database entry for MasterMinds Field Mastery.
The "Temp Invulnerability" entry is flagged internally as Personal_Force_Field and is marked for accepting Defense Set IOs rather than Resistance Set IOs.
Not having paid full attention to the epic powerset changes, I'm not sure if it's actually supposed to be a Temp Invul. clone or a PFF clone though.
It's described as Temp Invul with TI's power effects (+resistance), but it looks like the base power was copied from PFF and modified from there.
