I just won a game, but lichess tells I lost

I don't understand, I won a game with a pawn ending and lichess marks it as lost in middlegame?

My last game the same - white already resigned when I was kicked off the game and after coming back I was lost on time

Same thing happened to me with lichess.org/0vn19PzB. Played out a whole endgame, won by mate, then the site booted me off my account entirely and when I logged back in I'd lost the game on time, and half the moves were gone. Really bad outage.

I've seen things like this a few times now, it looks like Lichess crashed today for some time. I hope the developers can manually fix these things, but if there is no record of the game then it can't be proven if you really won it...
