At the beginning of my last game (Premier Draft Reality Fracture), no UI was showing on the screen allowing me to select my starting hand. I had to restart the client and rejoin the game in order for it to appear after which my opponent timed out and lost which leads me to believe that either they had the same problem or that the bug appeared because they disconnected at in a weird timing.
Fortunately the bug lead to my victory because my opponent was on the play but I'm afraid that had I been on the play I would have timed out myself and lost, which would have potentially ruined my draft.

I'm playing on PC but unfortunately I did not take any screenshots.
