Stone Slab

By Rodzilla68, in Mansions of Madness Print on Demand Expansions

In the "Lost in Time & Space" there is a stone slab. In the past or present, you have to solve the Alchemy puzzle. I assume, after that, you have to use the time machine to go into the future and then do another explore action (so THREE actions to complete this)? Also, after this the next clue says if you're not in the future, you have to go into the future. Well, how could I NOT be in the future if that's the requirement to explore past this?? This whole adventure is nearly impossible for the investigators. Tougher everything and don't even get me started on the final reveal!
