[kovarex] [0.17.6] Crash moving train station: "Rail::RailConnection::isConnectedTo"

Post by FeistyTeapot » Wed Mar 06, 2019 11:32 am

A crash happens when I'm moving a train station. It looks like a null pointer exception and my guess is that it's related to train pathfinding.

Version 0.17.6 running under Steam on Linux

Steps to reproduce from the attached save:
1. Send the train to next station
2. Mine the lower track left to right and the crash should occur when attempting to mine the first bend

How to avoid:
1. Send the train to next station
2. Finish the upper track before mining the lower track
