I sent this to Customer support as well, but I'd thought I'd give a heads up to keepers here.
The Errata says to replace Blood Pact with De Vermis Mysteriis (makes sense) and add Crucifix (possible issue).
The Seed Cards list Crowbar for Laboratory or Hallway 3, but Component Setup dose not list the Crowbar.
If you add the Crowbar and Crucifix, you end with one too many cards (not placing one in the Foyer as the setup says).
One can either give the investigators a break and put a Exploration Card in the Foyer or add the Crowbar instead of the Crucifix (or any other remaining Exploration Card after Seeding for that matter).
I also noted that Question 3A and the Seeds that reflect it seem to disagree. It dose not break the game, but if you want your choice to be reflected on the board, swap the Seeds for Master Bedroom and Bathroom (1 in the Errata).
