First, great job, having fun. After given Gren the first computer core and making a choice for the new Skydrop (I chose turret), the screen blacks out then I thank him and he says Sorry, busy now. Come back later. So I am unable to add the turret Skydrop to my ship. I tried this several times and was fortunately able to get him past this but rapidly pressing the E (talk) key. I was unable to reproduce this correction though.
