The more I play the beta the more I think the bots are triggering this bug for me, when I don't activate bots I rarely have crashing bugs (but I have nobody to play with to test anything either).
List of Actions I've taken immediately previous to a crash:
powering up
using turbo's hold function to temporarily superboost PL
charging up an attack
attempting to enter a struggle (via beam or blocking), especially if the beam is a generic beam in orbit around me.
These actions do not consistently result in crashes, so I think its a case where simultaneously some other event is occurring and triggering the glitch. They have triggered crashes more than once, however, which is why I think they're related to it somehow. They only seem to cause problems when bots are battling away in the background.
And people keep referring to the superbots, but I think they were disabled, I can't get any superbots to join the server,.
