HandyNotes: Midnight (Treasures and Rares)

Changed in v73

• Dust 'Em Off: minor coordinate tweaks in the third set
• Requirement text for "any of these" groups now reads as alternatives, rather than as if all of them were needed
• The map does less repeated work when it refreshes, which should help in zones with a lot of points
• Fix route lines sometimes not drawing again after an error elsewhere on the map
