Uh oh, thanks for the save, wouldn't be able to track it down with one
This has happened before with pathfinding, though it's usually due to simply having too many bots out there, and generally only when they're all after you but blocked off for some reason (like you're hiding in a completely inaccessible area), but in generally the pathfinding has been mostly sped up enough that this doesn't really come into play as much as it used to.
Still, if anything can slow down the game between moves there's a 99.9% chance it's pathfinding, and sure enough on profiling this save there's definitely an issue there!
More specifically, it looks like a follower (or probably more than one, based on the slowdown) is repeatedly trying to reach its leader, but the leader must've gotten blocked off somehow, perhaps stuck behind a wall you opened earlier? Anyway, now I have to try and figure out
which robot it is across the entire map which is doing this xD. Don't have any built-in ways to do that yet...
If and when I do find them I could just splat them for you and give you back the save so you could continue this run without the rest of this floor being so ridiculously slow
