|0003651||Dwarf Fortress||Undeath||public||2010-11-17 00:09||2012-03-02 17:41|
|Assigned To||Toady One|
|Target Version||Fixed in Version||0.31.22|
|Summary||0003651: Ghost appearing/disappearing causes a massive slowdown|
|Description||Whenever I see a "ghostly" creature and it appears and disappears (which leads to it appearing and disappearing from the list) my game becomes "stuck" in specified periods of time, leading to an overall massive slowdown.|
The moment the ghost is put to rest, the game runs smoothly again.
|Steps To Reproduce||Have a ghost on your map.|
|Correct. Suffering massive delays as the ghost blinks in and out. This is on the Linux version with a world rendered on 31.18.|

Same here on Windows. It's game-breaking until you memorialize the ghost, which takes forever due to the massive slowdowns.
For the record, the ghost that caused this bug was a caravan merchant who died.

It's not gamebreaking for me, though it's annoying. I've got a pretty good computer, so that could account for the difference, but I just get a pause of about 30 seconds to a minute. I have lots of ghosts going on, since I've had gratuitous amounts of death and am not burying or memorializing anyone.
It's still an important bug, though. This is probably the most annoying bug I've experienced.
EDIT: Okay, different embark, and it's gamebreaking for me now.
|I'm not taking a hit in fps or a pause. Windows and good system with i7 processor.|
|It's happening in Mac 31.18 too. Could this be connected to bug 0003708? I've had plenty of ghosts before (nobody from before the 4th migrant wave is still alive) but no problems until a "nameless" ghost showed up.|
|I have the same problem but it's very strange. I have ghosts on my map since the very beginning of my fortress when one miner got encased in ice while trying to pierce an aquifer. I've intentionally not buried or memorialized anyone to get ghosts and it was no problem until now (more than 3 years into the game now). Suddenly the breaks started (I have like 4 ghosts now) and got longer very quickly. Unfortunately it's gamebreaking for me too. Cpu usage goes through the roof and the game freezes up to a minute. The actual fps between the breaks seems to be ok. But the freezes seems to come every other step now. :(|
CapnRis also has this save from 0003815 that seems to be the same issue.
My bet: it is caused by pathfinder.
Ghost can move in all directions so
(a) it will path in (2*n)^3 cube to travel n tiles
(b) it is using useless for him cached data
(c) maybe part of ghost is not pathfinding, so it is why only part is killing FPS.
Solution - just move ghost without pathfinding.
And it just happened for me.
And it wasn't nameless ghost.
|I can report that it doesn't appear to happen every time I have a ghost. In some instances I've had a ghost quietly haunting the well he drowned in, and in others I've experienced incredibly erratic FPS issues. I believe it is related to ghosts pathing through unexplored underground areas. The reason I believe this is because the ghost was not on the unit list during the largest instances of lag, but by zooming in on it via the relationships menu the cursor centered on a point that could only be Hell.|
Same problem confirmed here. My game started to lag for no apparent reason and there were no visible ghosts in the unit list. I ran DF reveal and I was able to find the two spirits and put them to rest. In my case they were in conventional unexplored layers.
Carving up two slabs now so things should be fine.

|I think I'm having the same problem. 0.31.19, windows. Game started pausing 1-3 seconds with increasing frequency ever since my first ghost appeared. Right now it runs for about a second, then pauses for two or three seconds, then runs for a second again. At some point it seems to hang completely, and I have to close DF via the task manager. During the pauses, the game window won't respond to alt-tabbing et cetera.|
I just started getting the same issue
complete freezes for up to 30secs to 1 min at a time
had to forcefully close the process to get my system back from the game
On a side note, I hate the interface for engraving a slab. Here is a summary of my process.
1. units menu, find the offending ghost
2. remember/write down the ghost's name
3. open the craft workshop and engrave a slab
4. page through the MANY MANY MANY pages of names until you find the right one.
With my rather evolved fortress, I have several HUNDRED names to search through anytime I need to engrave a slab. Some of the names aren't even visible and simply say (engrave a slab) without any associated name.
It would be a HUGE timesaver if we could enter names to engrave with a partial alphabetical match like is used for ordering manangement tasks.

Another save, this one with definite lag and ghost activity.
Ghost appears on the western edge of the map, at ground level, in the stream.

|Ghosts, as non-material being, should not need any pathfinding at all. Just make straight line from x1,y1,z1 to x2,y2,z2. Maybe in some cases game incorrectly uses pathfinder instead of simplest case?|
