help I can't move my pieces

so I just encountered a weird bug in two games where I couldn't move a specific piece. I would click on it, but its legal moves wouldn't show (and no, it's not absolutely pinned) and I would be unable to move it.
It's probably a problem on my part, but I have no idea what causes it. It seems kinda random, as I am able to move the other pieces.

I'm not trolling in the slightest and pretty confused atm

Props to the OP for making it a beautiful video with appropriate BGM

This happens to me periodically on the first move of some games, particularly bullet. I have even tried right after to solve a puzzle and the puzzle won't let me move either. None of the pieces show legal moves despite it being my turn. I end up having to reset my device in order to fix it.

Did you report the bug?

you have multiple lichess tabs open at once could that be it?

why do you have so many tabs open?

check your discord btw
