I am also getting this error:
MathIsUnitVector(forward, 0.01f)
A serious error has occurred that prevented the application from continuing. A report has been sent to ArenaNet to help determine the cause.
Requires a restart to relaunch – Activity Monitor doesn’t show GW2 running. Happened twice two days ago and today it crashed right after character select. I went to this forum to read up on it and my Mac Pro froze…not sure if it’s related, but I had to hard shutdown. Sept. 13 was the first time I’ve had an issue with the client. I had, until then, played without issue, even after the Sept update.
Please advise. I’ve been enjoying the Mac client; I hope this is fixed relatively quickly. Thanks!
