Sometimes, when he runs into an obstacle in his path while chasing, he'll stop completely, even when the obstacle is removed.
This error message shows up in the console:NextBot [2661][npc_drg_fnaf2_witheredpurpleguy] Error: lua/entities/npc_drg_fnaf_aibase/shared.lua:99: attempt to call method 'CrawlMode' (a nil value)
I think he might be trying to go into crawl mode? Like some of the other animatronics do? Tested it with nextbots that do have a crawl mode on the same obstacle and they went into crawl mode, so I think that's probably the problem.
