Sometimes when I click on a station type (vanilla or modded) to try to build it, the game hangs for several seconds and then crashes with a "Fatal error: Assertion `clampedValue >= 0' failed":
I'm using CommonAPI2 and a variety of mods including several that alters stations and tracks (see stdout.txt) so I'm not sure how to start narrowing this down. Unfortunately I haven't figured out a way to reproduce this reliably, but maybe someone here has seen this error before?
