just finished it after maintenance, got the achievement but also did not receive the skill point

I just did it with 1 other person. Long after maintenance. Both of us got completion and skill point.

Here's how to do it*:
From the POV of the activation button there's a little shield(1) to the right in the sand. A shield(2) to left at the corner of that 1st platform. And a shield(3) far away on the other side where the gargoyle is.

step 0: Stand at little shields looking for clues. Find none.
step 1: randomly step on tiles with partner randomly stepping on different ones
step 2: kill ALL the things
step 3: stand at each little shield and look for clues.
step 4: realize shield 1 and 2 are gone.
step 5: Each stand on a different scarab
step 6: Each stand on a different spider
step 7: Notice shield 1 is now a sword
step 8: each stand on a different scorpion
step 9: 1 of you activate switch
step 10: kill 3(?) insect monsters, the guardians, which were triggered. Don't die
step 11:scorpion was much harder to kill than the rest, but didn't notice if named

Took us longer to find the puzzle than to futz around and solve it. Puzzle area is center west. Saw no lights but tbh I didn't look back at the activation button on the wall. It's 3 swords in a reuleaux triangle.

*Results may vary, no idea what is or isn't necessary.

you need to be at last 2 players, stand on a pair of symbols, to activate them, lights turn off.
after then go on for the next 2 pairs. finally 3 bugs spawn. these need to be killed for achievement credit.

Two players required.

Step on scarabs (one player on each symbol) *lights will disappear*
Step on spiders (one player on each symbol) *lights will disappear*
Step on scorpions (one player on each symbol) *lights will disappear*

Defeat the three icky bugs (a scarab, scorpion, and a spider)

Interact with the shields on the wall.

You should get a skill point and achievement.

Just did this with a friend, it works, thank you
