This morning me and another player from my guild went to do Tears of Itlaocol to get the achievement/chest.
We got to the area where you have to place the tears but there was only an image on the left hand side of the rock. We set the tears up and the room rumbled and the first torch lit but then were left at a loss as to what to do next since there was no symbol to copy on the right hand side.
The player from my guild ended up having to leave and I did manage to get through after a while by looking up video walkthroughs online and trying the combinations that others had on their stones, which was actually quite difficult because I couldn’t find any where anyone had the same left hand symbol as me.
But yeah, so I did manage to get through in the end after a lot of trial and error, but it is quite clearly bugged
