colony ships - impervious to minefields

[Moodai]

I was testing out a strategy using minefields at all the warp points. Mine level II with level III explosive. Setup a minefield with 70 mines in it - enemy colony ship wanders into it and totally wipes out my minefield with only 43% damage taken

Very impressive considering each mine should do 900 damage points!!!!!

It's rough playing against an AI with hulls made up of NEUTRONIUM.

Figured this was an anomaly so i did this against an enemy fleet of 15 LC with level V shields. They all got destroyed and i had some mines left over.

My new stategy is too not let enemy colony ships approach mt minefields
