Hello,
Well, when you change from 32bit v to 64 it won't get you alive because of memory problems that are still somehere there.
But, as far as I can survive that can someone tell me if you were in the moment, when you start the game with one big screen showing players and counters on left ? Sometimes I try to rejoin and I land like I were unaffected by the server, so I turn into spectator mode or I see player-table-bug which prevents me to do any actions.
Anyway, all these things appear after frequent alt-tabbing, so the device lost process and network syn.c isn't well suited for such actions!! ! More mechs maybe?
