I was playing a cup match and it was 0-0 until the final seconds when I scored a try. The game ended. No time for a conversion. Theres always time for a conversion !! In the real game the game wouldn't end until the conversion is taken. If a try is scored there is ALWAYS a conversion. Even if theres 110 minutes on the clock.
Conversions
There has been a conversion, there is always one. It can happens sometimes you can't see it if the match ends on it. This bug will be fixed in the next update. In this case, just have a look to the match replay, and you will see the conversion.
