Game crash and sheep causing giant jam

[Ronan]

I didn't find the bug tracker, so I'm posting here. I run 102.2.2 on Ubuntu 10.04 (install from the standard repositories). I've attached a save from a hands-off game which crashes reproducibly after a few game days, with always the same error displayed on the console log :

Code Select Expand

simutrans: simline.cc:48: simline_t::~simline_t(): Assertion `count_convoys()==0' failed.

Note also that there's a sheep in (299,729) that seems to have been stuck there for years and causes a giant traffic jam involving many hundreds of vehicles. While getting so many vehicles trapped is just another example of the AI's stupidity, the frozen sheep seems a real bug.

Thank you for the bug report.

You can remove the sheep with the bulldozer. These stupid sheep do not find a way from the street. Bug/feature undecided.

The crash is fixed in the next nightlies (rev >= 3856)

Alternatively you can try to remove the remove oil business of player 6 (purple) around (793,685), selling the train might be enough. But the crash can happen again.

City limits could block sheep from walking on the urban streets.

Another thing, yesterday I saw a miracle: sheep were walking on the sea.

should be fixed in the meanwhile.

If there is a way to remove all sheeps?

Or a button, that no sheeps where generatet at start??

I think there's an option for hiding ground objects at simuconf.tab.... :/

I guess you can also just delete the sheep pak file.

[Dwachs]

Yes, one can delete the sheep pak files  if one does not like them. Or use the bulldozer. They will never come back then.

[Ronan]

Thanks, that was quick!

AFAICT, setting random_wildlife_probability to 0 disables their creation.

The issue of frozen sheep aside, what I would prefer is for moving objects to have a finite lifetime and be generated dynamically. Is there a setting for that?

No (not yet).

I have had troubles with urban sheep as well. I wish there was some AI game warden that automatically killed sheep when they enter a town. When my vehicles end up trapped behind a flock on a road outside a town, I would like some notification so I can go take them out myself. The latter will not help much for sheeps in towns, because they are a pain to bulldoze in there. I usually have to bulldoze a bunch of pedestrians and city cars before I get to the sheep, sometimes also taking out stops in the process.

Another problem with sheep is that they often spawn inside a forrest (not the industry type) and can't get out. They just walk back and forth on a single tile (or maybe two). A tree or two should not prevent a flock of sheep from entering a tile. Either change that, or prevent sheep from spawning on tiles they can't get out of.

I am having the same problem except when I zoom in, the game automatically shuts off.

In your case the crash seems to be triggered by the zooming. Did you really get the same error message as the thread starter??

Which version of simutrans? Which kind of graphic pak? Operating system?
