Off Topic Productions

I just added an extra variable to ScriptedPawn.uc, a vector indicating the last seen location of the player. As soon as the state transition is made from Attacking to Seeking, that vector is updated with the player's current location, and the "seeking" AI routine is modified to check against that vector, NOT the player's constantly updated location. That solves the most blatantly bad problem, namely NPCs loudly dismaying over how they can't find you while they follow your cloaked ass from room to room. It also makes a lot more sense, since if real people were looking for someone they'd do a radius search around the person's last known location.

Alternatively, you could alter the "seeking" routine to use the player's real location initially, then go off of the NPCs location whenever a new search radius needed to be specified. That would stop the clustering effect of NPCs, though it would look a bit more disorganized.
