BUG !!!

I played a 5+3 game last night. On move 3 by black his time went down to 0 seconds. I was thinking I won on time, but notging happened like it froze. When I checked I lost on time, even my clock didn't count down. Really unserious by Lichess.

This is a connection problem on your end, not on that of lichess. See also lichess.org/lag and the large amount of similar questions in the forum.
