Automatic kills and combat cancel cards

[Mr_Draco]

I'm confused by the different rulings as well. Let's say there are two different scenarios.

1)
- Player A plays Churninator to auto kill a monster.
- Player B tries to play Friendship Potion to prevent the level from being gained.

According to Andrew, Player A would still get the level.

2)
- Player A plays Churninator to auto kill a monster.
- Player B wanders in a monster to keep the combat going.
- Player B then plays Friendship Potion to prevent the level from being gained.

According to Munchkin, Player A would not get the level.

Does the different rulings revolve around rather a monster was wandered in?
