Having problem with game freezing when i use weapons in battle, campaign and ranked battles. Tried relocating weapons to different positions, problem still happening.

Tried building 2 new mechs in bays 4 & 5, saved them went to chat. Decided to use them, relocated them to bays 1 & 2, no prob yet,, uh-oh game froze...
Refresh uh-oh crazy stuff,,, mech in bay 1 is overlapped with mech from bay 4 and overweight by 1000. Mech from bay 2 is completely gone and replaced by mech from bay 5.

Anyhow very glitched/bugged to play 7.0R for me HELP PLZ..


UPDATE;

Played my other account, all 3 mechs were working great. UNTIL i made a new mech in 4th bay, moved it 1st bay, went to play it in campaign, launched my drone, wait for turn, select a weapon,, game froze.. So i refreshed moved it back to 4th bay, tried my 3 older mechs in campaign again, no problems,, signed off, cool. Signed back on later, WTF,, my mech that was in 2nd bay, was now in 4th bay,,, crazy. So i moved it back, upon further inspection it was way overweight, it was merged with mech that was in 4th bay. Anyhow removed the double items to bring the weight down to limit and its working OK for now.

UPDATE UPDATE;

On this account, every-time i use my Twin Termination R the game freezes, doesn't matter where i place it on my mech and i have tried replacing it with other weapons too and some still freeze the game, some don't but the TTR was part of the original build and without the mechs just not right.

OK all my mechs freeze on this account;
on my 1st mech it's the Twin Termination R,
" " 2nd mech it's the Twin Termination,
" " 3rd mech it's the Blue Shredder Beam, that freeze the game
