I’ve yet to see a guide for this, so thought I’d post this here for people who’re still looking for them all.
This is part of a much bigger guide, but as I’ve completed the map I thought I’d share it now rather than later. Most are easy to find, but it should help give anyone who’s stuck a general idea where to look.
