Just went into a game of FW in Hellebore Spring, on my first mech I was suddenly disconnected.
Unplugged, replugged my LAN cable, re-fired up the game, rejoined FW game, and ran into no HUD bug.
Alt-F4, restarted client, logged in and rejoined match, OK, lost a mech and was on my 2nd. Nothing out of the ordinary. Then 2 minutes later, disconnected again, only this time I'm hearing my team mates voice chatter while starring at the log-in screen. I immediately re-log in again and the no HUD bug pops up again.
Quit and restart again and I'm suddenly down to my last mech. Lost that pretty quickly too.
A string of bugs in 1 match, restarting the client only allowed for a short time before suddenly running into the same problem.
