(suggestion) Have Invulnerable Envoys not trip Mines
This is a minor thing, and may well have been identified previously, but in the latest beta builds, the Envoys of the various races can trip mines while cloaked in diplomatic immunity. The issue here is a sort of economic sabotage, as the ability to send an Envoy into a gravity well ahead of an assaulting fleet to clear a beachhead for incoming invasion forces is possibly beyond the designed scope of the cruisers' functions.
It isn't the end of the world, but I have been routinely using Envoys to clear mines prior to assaults because, with diplo. immunity, they have a 100% of successfully cleaning out a small space before being pummeled to death by other mines or defensive forces.
That's all. THanks!
