Ok, so this was a match with 5 commanders and 4 moon like planets all of them were smashable given the correct number of Halleys. I went to one commander's moon and annihilated him, then I built a Halley on his moon and smashed into another moon annihilating two more commanders and it was totally awesome btw. Then things got crazy between me and the last commander and I was left with no choice but to build a Halley on my own moon because he was all over it except my base. It says ready "Thrust control established ready to annihilate choose planet" I open the drop down menu and want to send my own moon crashing into the moon where my enemy commander is located at, while my commander flees to the one I've already smashed something into thereby winning the game. THIS is where the PROBLEM is. In the drop down menu the only option I can choose is the one I've already smashed. So I think that the second time you smash it still remembers your first planet selection (maybe?) because it wouldn't let me select the other moon. Meaning there was no little red circle target thing next to the moon I wanted to smash, only next to the one I had previously smashed. Sorry that was a long explanation but I wanted to make sure you understood the problem. I still barely won the match 20 minutes later but I think it would have been really cool sacrificing my own moon to kill him and so I was a little bummed I had to do things the hard way.
