Sorry when I said 'any' it really meant I was too lazy to test. I've gone through the list to check which mods do and do not cause this issue.
Issue Caused (no type 9 camos):
Xandier's Kancolle Skin Pack 2
Akoi Hanage no Arpeggio Skins
No Rust Skins
No Issue:
RWBY Skin Collection
All 'Group 2' skin packs (KM ships, Yamato, Blyskawica, Nikolai I, Missouri)
No Manga
Invalid:
Unique camo for all ships (changes them anyway)
Camoflauge Remover
Crood's Skins
I've included the logs with only RWBY installed and the Type 9 camos working.
P.S.: I've noticed that 'Group 2' is inside of 'Group 1', but 'Group 3' isn't. Is this the intentional formatting?
