[kovarex] [0.17.21] - Crash within ~22s of loading vanilla save file

[akraziatic]

After updating to the latest experimental version, within ~22 seconds of loading the save, the game freezes unexpectedly. Have made 4 attempts where I changed my course of action and even stood still after loading the save, however the issue has been consistent.

Have loaded another save file and couldn't replicate the issue.

Not sure if it has any bearing, but in the problematic save I had recently put a large number of belts down, triggering ~300 construction robots and ~200 logistics bots.

Was having trouble uploading the save file so here is a dropbox link: https://www.dropbox.com/s/b06qo0fv2i7h3cb/V5.zip?dl=0

Rolled back to [0.17.18] as it was the last version that I experienced no issues. After loading up an older autosave and starting again have come across another crash.

EDIT: In case it has any bearing, the original is a save file I copied over onto my PC from a Mac.

Crash is from the same cause. Without checking anything other than the log, my guess is that there's a locomotive ghost somewhere that's trying to be built, but there's no track at the back end, causing the game to crash when it discovers that fact.

[akraziatic]

Thanks mate, I'll take a look. Could be the case as I'm beginning to build out my stackers.

[akraziatic]

Just found the train ghost. Will report back in ~30 minutes if no crash.

[akraziatic]

That appears to have done the trick. Should I close the bug now? Or will this be relevant for the devs?

[tehfreek]

It shouldn't be crashing regardless, so I say leave it.

[kovarex]

Thanks for the report. seeing the place where it crashed made it super clear what is going on .

The ghost managed to connect the front and back wheel to the rail, but there wasn't path between. This couldn't happen before train ghost building, but could happen now. I'm surprised, that this didn't happen more often.

Fixed for the next version.
