Crashed on that doughnut-shaped arena when building a trt.

Simply put, I wound up opening the build turret screen when I just bought that turret, and crashed.

If only there was some sort of getsatisfaction thing so I don't have to write paragraphs out of game to report problems as they happen. Natural Selection 2 has a thing with the Steam Overlay that lets you report bugs and problems almost instantly on F1.
