It's now happened twice. I think both times I was in an S2000 '06, and I was adjusting one of the gears on the fully-customizable tranny. I was tuning within the expert Seasonal Event at Twin Ring Motegi (FR non-race at 500PP max). The whole tuning sheet was a little touchy and seemed slow to respond to any inputs. Then in the middle of adjusting 4th gear, my system froze forcing me to shut down and restart. Anyone else suffering similar fates? This event (Twin Ring Motegi Seasonal) is my favorite grind-and-tune at the moment.
