Anders CG 3 is A13.
Lars CG 5, 6, 7 I believe is the Special Episode CG (Patreon builds for now)
Parker CG 3 is P13.
All of the Day 13 CGs (minus C13, that's Andrew) can't be unlocked in the public version as of now until their respective Day is released, so you've gotten everything more or less!
Thank you for your support :D
