After a new match started (we have won the previous match), I wasn’t able to join the prematch, select the mercs and pre-spawn. Instead I was given a 3rd person view of the spawn. The match started and I was able to spawn but HUD was still missing. Also vchats and chats weren’t working. I could shoot and change weapons, though no xhair or health indication. Dying and respawning didn’t help. Only quitting to main menu and rejoining corrected this.
I have no idea what caused it.
