3+ bug?

In this 3+ game:

http://en.lichess.org/a7CfULpj

I lost when my opponent gave me the first (and last and only) check. As you can see, the "checks given" readout says that he has given 3 checks but he has only given one in the whole game.

Is this Mr Bug roaming in the house?

It clearly appears that your opponent supplied 3 checks.

38. Bc3 h6+ 39. Kf4 g5+ 40. Ke4 Nc5+ 0-1

Consecutively, actually.

In that game you have linked you got check 3 times (moves: 38,39,40). So everything is correct.

3 checks given...

Oopsee! Sorry guys! I must have had a major brain malfunction! I even checked it 3 times (at least) before submitting this post...
