Nothing happens after reaching victory conditions

I have this problem: I'm playing a single player game with one bot and when I reach winning conditions nothing really happens. For example when I'm destroying enemy citadel its model is still there but it doesn't have hit points anymore so I can't do anything (exept walking, fighting the bot or doing something like that). When I'm playing CTF and I gather 10000 pts game just shows me center of a map for a second and then nothing - minions are still spawning, I can move around etc. Can anyone help me?
