In case you missed it, the transmog plugins got disabled with this game update since they're likely all broken runelite/plugin-hub@bf858c7
You very likely have to change the +512 to +2048 as a fix => there's a constant now in PlayerComposition.
FYI, you might also want to take a look at the new makeover updates etc. https://secure.runescape.com/m=news/a=13/slayer-partners?oldschool=1
