[No first Kuva Lich help!!!]

Yes I did a mission to receive my first Kuva Lich.  Got the animation and all.  Never met the maggot in that mission so I'm wondering if you didn't kill it then that mean you'll never see it?  Been running level 20+ missions and still no Kuva Lich.  "Iceemptysoul" is Xbox gamers tag

[Ayatan sculpture glitch/bug]

Played two missions to get sculptures.  First time I cleared mission I thought I forgot the sculpture so looked to see if I can run the mission again.  I saw I could so I was like ok I really must of forgot it.  Ran the mission the second time and made sure I picked it up and cleared the mission.  After completion I tried to trade for second time but again it wasn't in inventory.  Tried to look for a de administrator but it seems they have better things to do.  Can someone help with why I am out a sculpture after 2 run???
