Hello,
first: the phasestabilizers on a wormhole wont be used in my games. the ships passing the wormhole erveytime instead of the shorter was via phase stabilizer.
2. In my game the Advent Ai build a huge drone fleet with just homing mines. So they attack with 20 or more drone hosts without any figher or bomber, just Homing mines. AND: they dont use this mines. they just fly around with them.
So it was so easy to shut down the fleet again and again.
if a replay will help to track it down i can post one. (where are the rebellion savegames in the steamversion ?)
