Disconnect causing extra time bug

So I was play a bullet game and disconnected, and during this time I ended up reconnecting and disconnecting a few times, and somehow the game didn't end. When I finally reconnected, I noticed I had more than 4 minutes on the clock, in a 2+1 game. I have no idea how this happened but I think it's worth reporting.

Probalby a unrated game in which your opponent gifted you time. You can do that by clicking the "+" next to the clock.
