In the game lichess.org/B3yln59mhe8Z, which now seems totally normal on the server by the way, I encountered this problem: white moves were written in the notation as black moves and vice-versa. In the end I, playing white, could not make any move. I could drag my pieces, but when I wanted to drop them on a square I couldn't -- the pieces returned to their initial position.
The last moves of the game notation as I was seeing them were:
35 Bh3 g3
36 Qf6 Qxb5
37 Qf3 Qd5
38 e4
Note that Bh3, Qf6, Qf3 and e4 were in fact moves from black and g3, Qxb5, Qd5 from white. I have a screenshot of the game notation, but I don't know how to post it
I think this happened after I got during disconnected during the game.
