Index match abruptly ending, but why?

[Turbo_Trotldyt_R-Zone_64]

Several times in low risk I had this weird thing that match simply abruptly ends. As if time ran out. And it shows this weird message, about final time, or what was it. But there is a lot of time left, hundreds of seconds! And then it shows that we won screen because we had more points.
Does Index have somekinda kick-em-out-because-reasons thing? Or is this yet another Index breaking bug?

You lose 10 seconds for each point scored against you, even if you were winning and the time limit left was low, just a few points against your team would be enough to force an end to the match.
