For context, this was a 4 player game that had a member leave during the very first round.
After finishing a round of bullets, the remaining two players had picked their items. I was in the middle of something so I had remained on the item select box. According to them the round spontaneously started after sitting on the screen for about 45 seconds.
One of the other players (Player A) had picked their items but remained on the screen before the bullets are revealed unable to move.
For the other player (Player B), the game progressed as normal (besides Player A's turn being bugged), and when it reached Player B's turn they were able to use items and shoot the gun but it had no effect on gameplay. Live or blank, the shells would fire, not affect other players, and not progress turn order.
The image attached was my POV after the round auto-started minus a looking symbol that had replaced my mouse cursor.
