(A13) Stuck builder causes performance drop.

[Mihsan]

1. Circumstances: had some strange performance drop (constant freezes kind of). It was showing from 9h to 0h, then at night it was OK.
2. Found out that I had worker stuck between two wall. Seems like he was spamming some stuff to game's logic. At 0h he was going to sleep so performance was good until the moment he wakes up.
3. Expected: stuck worker not killing performance of the game.
4. Reproduce: build wall around your colonist.

I noticed someone walling themselves in before, though didn't particularly notice any performance drop.

I do wonder if colonists are walling themselves in more with this update. They get to a corner, build the walls to each side, then realise they can't get out.

I saw people stuck behind wall too. But exactly this configuration causes performance drop. Had this two times already.

Just had someone wall themselves in (twice), and it caused the performance loss.

It's a nice warning that something is wrong though, otherwise you'd just find a skeleton behind a wall a couple of weeks later

Phew, I thought it was the ol' late-game hitching making a return.

Could you upload the savefile? I've tried to do it, but I didn't notice any performance drops.

//edit: I've optimized construction job a little bit, but I'm not sure if it will solve the issue

Save file attached. See for colonist "Sparkles". Had to recreate this situation since I lost that save file. Also had to kill all plants to get filesize under forum's limit.

P.S.: This is also done on my 2nd PC, so this performance drop should not be my hardware problem.

Can confirm this happens,  it's a very small stuttering every few seconds,  like a split second lag spike.

Thanks for the savefile. The performance drop is caused by the fact that the stuck colonist is looking for jobs more often than other colonists. In order to fix this we would have to optimize all work givers. Anyway, it's not really a bug, locking.
