[Gui] Error while testing the gui.
« on: June 11, 2020, 10:01:39 PM »


Simutrans stopped working while using the vehicle list window, I'm not sure exactly when, just tried to open the "settings" window and it was already hung.

I can't replicate the problem, however I was using "gdb", hope this is useful to you.

The crash happens when updating the next stop/waypoint of a convoy that is not in a depot and has an empty route. The attached patch should fix it.
