New game unable to colonize some planets. Save game and quit restart and load game able to colonize all planets again.
Fleet command sentry and Guard unable available in new game. Save game & quit. Restart and load game fleet commands work fine now.
Managing stacked fleets is a bit of issue as in you don't know which part still has focus.
Small and Tiny games completely stable. 
Things you don't want to know about yet ! 
Modded files to play a LARGE game. become unstable after after 3 hours. At 4 hours couldn't continue. ( I think I spammed to many medium hulls )
Couldn't get HUGE game to go at all. Crashed at creation stage.
Frigate ship icon missing in build screen
Colonial farm not upgrading to Xeno farm
Food distribution center ( I think it's called) build icon missing Builds ok and can see it once built.
