I cant destroy the Mothership . The hull is down to zero and she should be destroyed but it's not. All other mission goals have been achieved.
The Mission is "Closure" And "Checkmate" Anyone els run into this?

I am editing this a couple hours after i posted it. I begrudgingly went through the whole mission again and it didn't happen the second time . This time i didnt take any Mercs , now whether or not the mercs had anything to do with it , I dont know . All I knowis it worked the second time and tbhe mothership blew up.

I'm sorry to hear that. I hope you won't have any more problems, but if you do, please mail the log.txt and game save file from your folder to customersupport@starpointgemini.com so we can check it out and see what happened.

And I really apologize for the reply delay. :(
