Describe the bug/issue

while playing a round of tetra league the opponent board dissapears (it falls off of the screen) as it does when one loses, even though no one topped out/disconnected. the game goes on as normal and garbage still gets sent and received but just without the opponent on screen. in the next round after the bugged one everything goes back to normal.

Reproducing

No response

Expected behavior

the board shouldn't fall off if no one topped out, the expected behavior is the game going on normally.

Screenshots

Console logs

No response

Additional context

the first screenshot was at the moment of the bug and the second shows that the round kept going after that (replay is saved correctly, doesn't show the visual bug).
