New crash

[neroden]

This time attempting to sell a road vehicle.

I believe that the road vehicle was originally created in a different depot than the one I was selling it in, if that's interesting.

Sorry, no save file -- it crashed a sufficiently long time from the last save, so that the last save file doesn't even have the vehicle.

EDIT: Have I got a save file for you!  I managed to reproduce it.

http://files.[ simutrans [dot] us (site down, do not visit) ]/files/get/AzIzn9Mh8H/autosave01-potential-problem.sve

There are ghostly horses driving across the depot even though they're supposed to be somewhere else. The depot can't be deleted; the horses can't be sold.

EDIT:  ohhhkaaay, extra weirdness.  Loading the save game appears to make the problem go away.  So it won't show up in the save game.....

Hmm, very odd. The ghost vehicle problem tends to occur when a vehicle becomes detached from a convoy outside a depot. The problem appears to start in a vehicle destructor. Are there any specific steps required to reproduce this?

I haven't been able to pin down specific steps.  The weirdest part is that saving and restoring "cleans it up".

Very odd...
