Lost City, Na-Totambu, Spider, Scarab, Scoprion Solution

When looking for the solution for this, I had little sucess. I just did it in game version 1.3.4 and I thought I write it down once so it can be found by others. Details about the riddle in the spoiler tags.

The archievement is based on the bosses being killed.
They will not spawn until the riddle is solved, but if others solve it you can just "catch a ride". You don't need to solve the riddle for the Archievement, you just need to fight the bosses (as usually for dungeon bosses and with the usual rules for getting "kill credit").

There are 6 plates, 2 plates for each of the 3 animals.
Over each of the plates is a light column (plate light)

The bosses spawn when the lights of all plates are offline.

The light for one set of animal plates go offline, if both plates of this animal are being stepped on at the same time (you need two players for this).

The animals plate-lights have to be disabeled in order (nothing happens if you step on the wrong ones). For me the order was: Scarab, Spider, Scorpion (outer ones first, inner last).

After the archievemnt is completed, the crest on the wall started to glow and could be used (E), but nothing happened on doing so. Propably the animation/dailog/whatever should happen on use is bugged.

Hope that helps.

This puzzle gave so much problem to every single person who tried to attempt it in the past simply because *cue surprise music* there was a bug where after the first time the challenge is completed, the puzzle never reset itself (i.e. missing blue lights, nothing happens after the correct order has been attemped countless times by other groups, nothing happens after the players kill the bosses which seem to have spawned randomly etc) until the next maintenance arrives.

Which explains why there are so little solution online, often with vague descriptions (look over at the reddit threads). Soooo little people has a clue that they were supposed to see blue lights emitting from the plates, no one figured out it was a bug. No official response either despite the issue being highlighted multiple times by frustrated players trying to complete the challenge.
