Re: Mine effectiveness
 

I've noted that in one of my battles I dumped mines on one of my planets. Combat began and my colony was destroyed because I mis-clicked on the fleet's destination. The Mines did not activate until after the colony was wasted.

I made a quick test and the mines did their damage before combat. Can you reproduce the bug?

Mines don't explode unless you move into them.
