A Help Wanted notice in the hall: press E there to invite a friend to your museum.
Open your museum to the public from the same notice so anyone can join, or make it friends only again. The host can send a guest home from there too.
Twelve new achievements: for co-op, the shop, rare finds, the survey stand, the Zephyr's glide, the Aegis, today's dig, sliding through a chase, tunnel finds and completing the museum.
Every exhibit now has its own themed stand to buy in the museum shop, not just the Seer's Eye and the Rosewood Casket.
The museum board now ranks every museum as it grows, not only finished ones. Win a round and you'll see where your museum stands.
A hitch while the final screen was up after completing a museum.
Earlier finished-museum scores don't carry over to the new board. UPDATED SO THIS IS NO LONGER THE CASE, OLD SCORES REMAIN
