Hitman 2 the ninja disguise (but not in the outdoors Japanese missions due to their special AI), the fireman disguise in Basement Killing or the SWAT disguise in Hitman Contracts
I distinctly remember the ai spazzing out for no reason in all three cases
Got only Contracts on my computer right now, but I
got you an example to the contrary.
However, this is a bit of a bad example because it's notoriously difficult to actually get a SWAT disguise in this mission. The only way to get the disguise without an alarm is to glitch, because each SWAT is wired to some of his compatriots via some mental link. This means that when you turn off the light in the building in Hunter and Hunted, you can bump into the SWAT all you like, but you aren't allowed to kill one (you can't use Syringe on the SWAT members, so the only way to go is Fiber Wire or a bullet to the head), the rest of the SWAT in a group instantly swarm you. The only way to prevent this from happening is to glitch them into a "confused" state - most NPCs, when silenced weapons are fired at their feet, either run away or go into the aforementioned state, or both, but the SWAT don't behave like normal NPCs, and the only way to do that is to turn off the light in the building with a very precise timing or have them get shot by their own SWAT compatriots
while they don't see you. When this happens, you can strangle them and their friends don't notice. SWAT also do not trigger "Body found" alerts. With that in mind, I replicated the method by using Invisible mode, took the disguise, then walked away from the scene and turned the cheat off.
