I failed to find any info in many help pages I have visited.

The only related data I found is about WEB MINEFIELDS, it says the Crystal is inmune to all races minefields (they are the only race who can lay them but what if the identity was enemy).

This specific statement makes me think I am right and minefields launched from my ship with enemy (I mean neutral) identity will also damage my own ships, including the minelayer itself.
