Summary0003869: Drop in FPS when moody dwarf can't path to workshop
DescriptionI had a group of immigrants arriving, but they decide to appear to the map in location which has no access to the fortress due stream running between them and the entrance. One immigrant got moody soon after that, and I ordered the correct workshop to be built while waiting the bridge to get ready for migrants to get over the stream. At this point everything was normal, FPS was somewhere between 250 and 300, it's still young fortress after all.

Now, immediately after the workshop was ready the FPS dropped to between 30 and 40. The FPS stayed at those numbers to the point when the bridge was finally ready, and then it got straight back to the 300.

So, my conclusion is, if you have moody dwarf, and there is correct workshop but the dwarf can not reach it due block or something (in my case stream), the pathfinding goes wonky and the FPS gets major hit.
Steps To ReproduceHaven't tested this out yet but the steps could be the following:

1) Get moody dwarf
2) Block the path to the correct workshop with something (don't know if it must be land feature or if anything goes)
3) See the sudden drop of FPS

Another example of pathfinding updates causing lag when items are inaccessible. Ostensibly also related to the better known 0001340 but 0002945 seems more relevant in this situation.

Reminder sent to: Kipi

If you have a save demonstrating this problem, please upload it to [^]

What kind of mood does the dwarf have?

Without further updates I'm resolving this report. Also the relations to this report could also cover it.

Relevant save file, log file fills with pathing errors, just fills.

path fail: dwarf,Strange Mood,136,96,109 -> 69,117,109: Id 0005291:Path Goal Set Mood Building:Station Milling

Vampire can't path out to a workshop so the game is constantly trying to find him a path. The constant runaway pathing lags the simulator down to a crawl.

It might make keeping vampires as bookkeepers or some other noble tricky, having a strange mood hit them. Worse yet becoming "insane" from failing it and not being able to die of thirst.

When released to craft, I dug down deep enough to get the needed components, he finished making the item and right away went to drain a dwarf before I could put him back.

Reopened awaiting a save from Dwachs.

Here is the savegame: [^]

It is centered on the moody dwarf. She is walled-in due to were-infection, and thus cannot reach any craftdwarf's workshop. There are 3 present, but not reachable for her. FPS drops to 6. The FPS drop is also present while in were-form.

(In my game I waited until she transformed and went back to dwarf form, then opened a way to a workshop, where she eventually completed an artifact.)

Loci - meant to post a save, but was in a rush at the time and forgot. Seems like you found it anyway though :)
