Twice this evening, on the Canterbury server, the game has kicked me out whilst I was interacting with a newly built rail line "Wilcaster Flyer". I can rejoin as the game has carried on running, only when I've gone back in, the Line I made is still in the Lines menu, yet the single train I had operating on it, has vanished. I know the train existed because the line is not white, and in the depot are some vehicles I purchased in error whilst buying it.
In both instances, the train had reached a station and was unable to proceed due to a tiny unnoticed break in the track, which I fixed, then a few seconds later it crashed. Presumably when it retried to find a route, and succeeded.
I don't have a save for it but Asaphxiix might, the timestamp would be around 21:34 GMT.
I thought I should report the weirdness in any case.
This is consistent with the server crashing (it restarts automatically after a maximum of 2 minutes after crashing/stopping). I have just fixed a bug that might cause crashes in these circumstances. I should be grateful if you could confirm whether this is fixed with to-morrow's nightly build.
