[10.x] stuck to depot causes crash

[sdog]

stuck vehicles that were teleported to depot often have impossible consists in depot. Trying to sell them caused a crash.


I also very much suspect those vehicles are responsible for unrecoverable savegames, reported earlier.

Interesting. Do you have a saved game in which you can reproduce this?

Edit: I was unable to reproduce this when using the demo.sve of Pak128.Britain.

[el_slapper]

had the same on a previous save(and version). It was only for electric locos, though. Not sure I have the save anymore, I'll have a look this evening.

a few minutes later saves are not recoverable anymore.
check trains on line
341 bristol - reigate
they got "unstuck" and are in depot now.

Can anyone confirm whether or not this is fixed in 10.13?

I've encountered some crashes in the depot, it seems to happen if I sell a vehicle then try to buy a new one, clicking on it crashes the game, happened a few times (also in 10.13) but I have not been able to recreate it. It may have to do with the above.


Also, I can't find the original report, but I should report that the block reservation bug seems to happen in 10.13 as trains still get stuck and need release with 'b'.
http://simutrans-germany.com/files/upload/bug1.sve - this is a save of it, but the scenario seems the same.

Thank you for your report. Would you mind posting the second item as a separate thread? I might end up forgetting about it or not properly tracking the problem if it ends up in this thread. We need one bug report per thread if possible - it helps with management of issues. Thank you!

Edit: I can't reproduce the blcok reservation issue with your saved game and 10.13. Can you give more detail, or steps to reproduce...?

[asaphxiix]

sorry james, no problem!

[jamespetts]

Can anyone reproduce the original crash, or is this solved?

I don't know if this is related, but sometimes convoys won't go to the nearest depot or get stuck on a "retire" command.

http://dl.dropbox.com/u/17111233/client3-network.sve

Steps to reproduce:
1. Go to Nutish
2. Switch to ant fleet
3. build sailing depot at 891,753
4. tell ship (6484), which is just off the coast, to retire
5. It should now become stuck at its final destination

Also peculiar, send any of the ships waiting at Nutish to "go to depot" and it won't head to the nearest depot, which was just built at Nutish.
