Promotion

I forgot to save the screenshot after the game, but I was about to promote a pawn  with the selection open which piece to promote to in an arena tournament when my opponent resigned. That got the promotion selection stuck on the screen in the next game.

Obviously it obscured the screen, so I clicked on it and it disappeared without giving me a queen, but then I couldn't move one pawn. I don't remember exactly but I don't think it was pinned, it was fairly early in the game and the bishops weren't out, so it might have been the pawn that I was about to promote in the last game got stuck.

Either way, the second part would be solved anyways if the promotion popup doesn't get carried over to the next game

did you refresh the page?

No, haven't tried refreshing, but there were no issues the game after the next, just got carried over the first time

hmm that's odd

Weird. I will try to work on it. 

I'm not sure about the second part but I do remember not being able to move one piece with the time running, but it should be easy to replicate if you have two consenting players where one lets the other move one pawn to the eighth rank but to make the promotion selection show up but not selecting any piece and for then for the one not promoting to resign, and the one promoting starting going to the next match, at least that's how it happened to me.
