Sometimes some bets do get cancelled for some reason, I don't really understand what the reason is but most of the time it is these Asian side games, Australia believe it or not could be one of the asian part of the issue, I know its a whole continent of its own but what I mean is basically non-eu games and non-nfl/nhl games.

So, that could be the reason, to be perfectly honest with you I have never seen a champions league game or a premier league game get cancelled at all, ever in the history of nitrogen. That is why I think nitrogen has a serious issue with their game provider on the east side of the world, the previous one I saw was some Asian game as well so on games that are super played and known they tend to have weird odds and than they cancel the bets and redo the betting again. They need to fix that.
