oh wow... thank you for replying, atleast now I know what happened XD.

Hi everyone Before Kotfe-update I learned to craft advanced white-purple-blue and advanced white-yellow-orange hawkeye crystal. These 2 show up in my artifice crew skill. Now after the update I went back to the trainer at the fleet, hoping to learn to craft the indestructible versions of these. I saw that the 3 versions of these crystals I still had to learn (indestructible, eviscerating, war hero) are not there. My question is, were these not there before the update (I might think they were there, when they weren't XD) or did they disappear since the update? Or do I have to do something special to learn these now? Thank you!
