Random intense frame spikes when you have your imps locked up

[Tasosgemah]

This happens whenever i lock up my imps for long enough to protect them or stop them from exploring. I usually protect my high level imps for gems only and create some fodder level 1s to do the dangerous jobs. But when i do that for long enough (not immediately) the game will do these frame spikes, very hard ones, it feels like shader cache stutters almost.

I think it happens when the locked imps are idle. Not sure if it ever happened when i locked some imps with a gem block to dig indefinitely.

I'm using a recent 1.4.0 alpha.

Definitely a well known issue, and you're absolutely right that it is a combination of Imps + Locked Doors. Pathfinding is just a headfuck to deal with, so it's one of those things that has been repeatedly pushed to the side.

Create a map in Unearth that displays the issue as soon as you press Play and I'll fix it.

Each iteration I made to the map made it slightly worse, but adding the special boxes made it significantly worse.

Seems like the stutters have been fixed when it comes to locked doors, but it still get them when there is a different obstacle, like a lava pit.

Taso does seem to be right. Locked doors are a non-issue now, so huge credit to Rain for that, but lava still kills it.

This map also shows how bad creatures can be at navigating tight corners + elevation, as Imps won't even succeed in the East and West directions.
