The game looks to have hit some sort of bug when I checkmated my opponent. It keeps refreshing, and didn't give me rating points even though I won.
lichess.org/UhEvIeJJEBXXSomeone else also experienced the same thing as mentioned in his recent post. The time of occurence is about the same as your game.
In his post, I also said other problem happened in a Swiss rapid tourney.
Yes, I am having the same problem.
@NimaMacheavelli Maybe your opponent had been banned at that same time, because now I find his account closed.
