Possibility to "Cancel" Divine Intervention

[DojimaDragon]

We just had a game which was (quite munchkinly) resulting in a loud argument which was solved by the last word of the game owner. But I'm looking for a general solution.
The problem was caused by the card "Divine Intervention". The card was drawn face up and would have ended the game by raising a cleric to the 10th level. Another player however chose to play the card "Steal a Level" within 2,6 seconds after "Divine Intervention" was drawn to steal a level from the cleric the moment, Divine Intervention takes place. I, being the cleric, argued, that the 2,6 seconds rule only applies to combats. The game owner based his argument on his right to play the "Steal a Level" card ANY time.

I'd like to have either your opinions or preferably a definitive solution to this problem. Thanks for your input!
