OK, I ran it threw a secound time to see if I could reproduce it. Happens a bit after I add bounty to impending pirate raid.
I dont see why it would not work with entrenchment. I used the entrenchment files to mod (although I had to grab a few of the vanila files (IE RESEARCHSUBJECT_MAXCAPITALSHIPSPSI7.entity) from the vanila gameinfo folder becouse this file was not in the entrencement gameinfo folder).
***Edit also wanted to add that the only files I changed where the ones inside the gameinfo folder. I did not change any sounds, UI or gfx's, Or add new stuff, was basicaly changing some planet, and ship stats, Max caps and fleets.
