#1 Extreme delay starting new game after victory
After clicking [End game] on the victory screen, I tried starting a new game but it only showed generating galaxy till no end. So I restarted SiS and start a new game and everything was normal.
#2 Many times after [Bombard All]/[Destroy Planet] screen, can't make any fleet go anywhere (right-click to show path to other stars). And I can only get out of this strange 'mode' by (left)click like crazy at blank space until the entire galaxy screen go a slight flicker and things are back to normal. This has been happening since many updates ago.
