Thanks so much for the fix. I wasn't sure what I was doing wrong.
When the Scourge spawned (about 1/4 of a medium size map) away only a little while later did the "Queen" quest spawn. I sent a construction ship and a science ship to wormhole straight there. Basically ninja'ed the queen ship out. I was fighting one of the biggest factions at the time but I noticed once I took the Queen, they stopped expanding for the entire time of my other war. When I turned to focus on attacking them, they did have other Queen units fighting me.
Anyway, after installing this mod, once I got the planet to 0, a few seconds later it would be abandoned and I didn't have to set bombardment to "high". It also worked from a save so I didn't have to start a new game or anything
Just having a little trouble clearing them out because when they lose their influence and another faction's takes over, it forces me to leave and sometimes that "force" is make 10 jumps where I can't stop it. Oh well.
Thanks again!
