Kuva lich not dropping any weapons

[StikerLP]

I Killed my lich just now and it didn't drop any rewards??? Why did this happen? Please do something I worked Soo hard just to spawn him and getting the mods and grinding please do something 

Please look into this matter 

I'm sorry this game means alot to me and this bug totally breaks my heart😢

Look information about this lich in your Codex. You probably converted him and thus didn't get weapon from him.
