We just published a hotfix / maintenance to JS Live. Please keep in mind that as a hotfix and not an update, this does not include new content but rather addresses some issues that have cropped up over the last week that we wanted to react to ASAP for you guys.
the hotfix notes are short and sweet:
fixed a server crash scenario
fixed several crash to desktop scenarios
ongoing anti-cheat/hack countermeasures
Please use this thread to report any issues you're experiencing on JS Live.
