The only thing I can think of is the timeout on “MoveToFinished”. Specifically when you’re waiting on it at the end. You have to continue calling the MoveTo before the MoveToFinished to give it more time to catch the player. I’m a little rusty, so forgive me if I overlooked something, but I feel like I’ve a similar issue before. It’s also roughly 8 seconds from the NPC’s initial engagement with the player to when it freezes, which is why I thought of that. Hope this could be of some help.

when i’m out of office he will keep chasing me so i don’t think its MoveToFinished Issue

I just noticed the output in the bottom corner. It seems when the NPC hangs up there is a spam of “bobby getting waypoint Paths” in the output. Looks like that is being printed when the event is fired from when the path is obstructed? Try checking how you reassess the path after it’s been broken. (Edit: looks like when the path is blocked and the loop continues, it’s trying to get too many waypoints too quickly)

he can catch the player only if player is outside the office even if its on another side
but if player is in the office he just breaks https://streamable.com/krdbqz

Are there any unions or can’t collide parts in the office that could be interfering with the AI? I’m thinking it has to be something with the path blocking function. If it only happens in the office there’s a good chance it’s building interference.

i already fixed it thanks i just made the doors bigger

Yeah. For the future, two walls that are too close together can count as a wall to the pathfinding AI. So for instance, the sides of your doorway, the AI was seeing as a wall but still trying to follow you and that’s why your blocked function was firing. I assume it started working again when you left the room because it established that there is a path out? I’ve heard of the parts being too close before but not of it fixing itself. Interesting bug though glad you got it worked out.
