You have 3 add-ons with syntax errors. Not really a major problem since Torque doesn't execute them, but you may want to fix, delete, or move those somewhere else for the time being just to clean your game up a little:
Script_Friends
Script_EditBot
Script_ConsolePets
Next, Script_AdamBot is giving off tons of "break outside of loop" errors. It will function since Torque ignores them all, but it is also spamming your console. You may want to fix, delete, or move that one too.
Finally, the game-crashing part. Before the error spam, there is this message:
base/client/scripts/allClientScripts.cs (17275): Unable to find object: 'NoShiftMoveMap' attempting to call function 'pop'
BackTrace: ->[pick]NMH_Type::send->[buildChar]NMH_Type::send->[IGSO]NMH_Type::send->NMH_Type::send->[RTBC_IRCClient]Canvas::popDialog->[CanvasCursor]GuiCanvas::popDialog->newMessageHud::onSleep
I have no idea if they're actually related, but it's a start. The backtrace leads through IGSO, and it's causing a problem, so I'd look into IGSO first. If this does nothing, put trace(1); in the console before joining a server and send that to us.
