Co-Op Weapon/Implant Bug. Lose everything
Not only did my abilities re-arrange without me doing anything, but when I entered co-op all of my implants and equipped weapons disappeared. I beefed up all my guys in between co-op rounds so we could do medium (spent all of my cash on implants and crafted weapons), and then had all of the starter weapons and no implants. My bruiser went from keys 1-2 to 5-6. switching places with my slayer. This caused me to immediately stop playing and abandon the co-op session with my friend as we had a really difficult time in the next difficulty level.
It really stinks losing all of the implants and weapons you just used all of your money on crafting! And having underpowered characters when you shouldn't! Enough frustration to stop playing for the night and probably until the bugs get fixed!
