I did 45 turns in 35 minutes on a gigantic map with tight clusters, 12 Major Races and abundant Minor Races. It seemed to run faster than Beta 6.0. In the Battle Viewer, the missiles did hit the ships.

I could see pirates move in an area I had visited but could no longer see.

I will submit a ticket on this with a manual save game I made at that time and the debug.err as it existed at that time.
The second battle I had, Pirates attacking a starbase, the battle viewer had a black screen and had to use task manager to shut down GC3. There was no crash dump file generated. I will submit a separate ticket on this including an autosave one turn before the battle, thedebug.err as it existed while the Battle Viewer with black screen was showing in GC3 and the file generated by the SD Support Tool.
I decided to verify the Battle Viewer problem, so I restarted GC3, loaded the autosave from one turn before the battle and continued with the game. When the second battle was repeated, the battle viewer worked correctly this time.
