Hope it helps  

May be, but not that I know of, sorry. If there was I would add it to mine. I'm still testing my newest version of my mod and adjusting it. Will post the newest version when done and if I get permission from ScrivenerOfLight . My mod is a combination of the games anomalies, the wonderful "Resource Mission Mod" for the Crusade expansion of ScrivenerOfLight, the original Deathwynd 's "More Anomalies", the  anomalies that Horemvore uses in his excellent mod "Galactic Star Trek", and other anomalies I've added. I want an anomaly mod that is as big and diversified as possible, and hope to keep it growing.
