I don't get what the game wants me to do here (see attachment).
It's a nine lever puzzle where you have three given symbols and four switches which influence which symbol(s) one can influence. I managed to recreate the three symbols through some lever switching trickery but nothing seems to happen...

Go into first person, and use long range skill to hit the bottom right most pixal of the green X.

I guess I'll redo it according to this youtube video:

There the "x" on the right gets magically adjusted so the drawing style doesn't show a straight line anymore but those "loops". It seems it doesn't want to do that for my solution in the top left corner although I don't really understand as to why...

At this angle of view..it look like you missed a \ at the "riddle-symbol" at the right side.

Is this one of the early riddles at the vault of the goldmongers?

I'm at the one with four different sets of this. When did I appear in puzzle hell?
