Two weird events

[MercenaryForHire]

Checking in as another "Weird performance drops" member here. Mine got cleared up a bit by installing older NVIDIA drivers. What are your system specifications?

The AI being stuck, as Thomas suggests, would definitely explain why my framerate went to single-digits during combat, but would immediately jump back up. Either there's a broken bit of code in there, or there's entirely too much going on for a creature that only needs a few states - Patrol, Attack, or Run.
