Missing one Carnal rune!!!

[el_pieablo]

Well got to the last carnal rune using the guide and the achievement didnt unlock. Crap...

This was me using the guide too. Not sure if its one I have missed or if its a glitch, but was almost 100% sure that I have collect all the red runes even the extra one before travelling to the ice land.

Dont know if I can bring myself to play the game again, for the max carnal achievement and for the missing rune.

Furthermore the guides listed on the forums here for protecting the relic do work. I managed to get it on my fifth try so anyone in the same boat just keep trying it. The key is killing one or both trolls with the second boulder!
