speedcoop problem

played speedcoop trying to get high score got to round 480 game ended and it has not logged the game stats anywhere

The rounds are not endless, after two hours the game is over (480 rounds). There is nothing about skill to wait while the towers kill every creep.
The big combo modus is unbalanced in this way, the number of creeps should increase but atm it is possible to survive everything, until the game is over at round 480.

my problem was not that it ended it is that on my recent games list it simply is not there for some reason
