[HanziQ] [14.7] Crash when changing rail on: "RailPathFinder::findPath"

[DutchJer]

i had the same thing, twice today during the stream.

both were on the same line.

i can share the last savegame i have of the last one, but it's big, so let me know if you need it.

my logfile is here: http://pastebin.com/QrUSGaEM & http://pastebin.com/hNGxejJd

[Helfima]

i confirm it crash every time i can't play more than 1h

[MrGrim]

Ya this one appears to be unpredictable. I'm experiencing several crashes per session and specifics of signal placement or how the rail is being extended doesn't seem to matter all that much. I could try to hold on to saves each time it happens if you don't already have plenty.

[Zeno]

Experiencing this also.
At first i was running around, doing all sorts of random things setting up a train stop blueprint, then it crashed:

The next time i loaded the save i immediately placed the station blueprint and it crashed:

I've tried this for a third time and for a while it seemed stable, but then surprise, RailPathFinder::findPath happened again.

How to reproduce the error:
The autosave probably has the car inventory open to start with. Just open the car if it's not, and take out 2 concrete and 1 hazard concrete to your inventory that's needed to finish the "train station" blueprint you'll place to trigger the error.
Select the blueprint book and scroll through until you see the train station. Rotate it so the side branch is facing left (west) and locate the station so it's matching the existing track (the top and bottom most signals should overlay the existing signals) and deploy it there; the construction robots should start working on it.
During this time the iron ore train that's on the loop should probably have left the station and pass by if you were slow. This might or might not be the relevant train that triggers the error; there is an ammo train and an oil barrel train running elsewhere.
Once the station is built, wait a while; it should crash eventually... like it has the last 3 times i've tried it. Usually within a minute or two.
Edit - Did i say it might be the train? I meant it is the train. It can also crash immediately during train station blueprint construction if you time it correctly, just as the ore train is leaving the station and the proper tracks are placed by robot.

Damn, just lost my game due this, and now we got an update

[Gouada]

Hey MrGrim,
This is off topic but could you send me the updated auto-deploy destroyers mod? Been looking for a .14 version for a while.
Many thanks!

I released the 0.14 version a little while ago .
