Game Breaks after Reducing game speed

[Soulbulb]

I discovered this game breaking thing after i wanted to slow tiny tina down. The Problem with that is, if you try and slow the game down while you are in her hideout at Tundra Express, the Game breaks and you get the restricted area warning. It can't be fixed by resetting or walking around, if you walk aroud you get in an infinite death screen that repeats over and over. Only option to get out of this is save quit or closing the process. Maybe it only occurs while you are in the story mission on tundra but iam not sure.
