Hello. I want to report a bug. When you are on a Lichess study in sync with other students and you go forward in the game just a bit faster than 2 or 3 moves per second forward, the position returns to a previous position. Conversely, if you want to go back to a previous position at the same pace or higher, the board automatically takes you to a later position. And this is not related to other contributors because I've tried all this when I was alone in the study. This bug doesn't apply when you turn off the sync mode, which makes me think that the problem is related to connections between contributors and players who can't move in the study. The same happens with the arrows and circles if you draw two arrows one right after the other, the second one either is not drawn or disappears and appears within a second. This bug is very annoying when you are giving a lesson and I noticed it yesterday. I hope you can fix it. Thank you very much!
