I am regularly being attack by members of Galaxy 7. I cannot even damage most of their ships despite all my research being as high as it can be. I view the battle and I am fighting ships I have never seen. In the last battle, it looks like I am fighting a mobile fortress. I am only at level 22 Control Center on main planet and I only just got it there. From my understanding a mobile fortress is not available until Control Center is at level 26.
There is some kind of glitch that allows Galaxy 7 to milk planets that should be below their range. I am being bled of resources. PLEASE FIX!!!!!!
