AoZ Lohk Surge spawn bug

[PaladinMaximus1]

I just completed Angels of Zariman and soloed my first bounty (Exterminate).  I spent several hours searching for every single Voidplume and special spawns, even found a Somachord.  HOWEVER, once I killed everything and "Find and activate Lohk Surge" popped up the item did not spawn in.  I then spent over ANOTHER hour running back and forth scouring every surface and area but no spawn.   Then I decide to check Reddit and discover this is a common issue??  STILL???  Over a year after launch and this hasn't been fixed yet?

I don't think I'm any more special than any other player, but I have literally spent almost, if not over, $2k because I enjoy this game and do not have time to farm everything (i work a ton of hours and this game was my relaxation away from work).  However, I will not waste my time on a game that literally wastes my time for nothing
