Unable to Select Different Weapon or Change from IR Vision

Platform: PC
Map(s): Backwater
Class/Skin: City Hunter
Issue: While playing the match everything was working just fine and then once I downed 3 FT members, I could not switch from IR vision or even switch weapons. Only movement keys responded. After about 45 seconds of this, the game disconnects and I am greeted with the lovely network connection lost error (connected via Cat6 directly to modem and didn’t lose network connectivity to my PC or any other applications).
