Baubles - Reborn? (1.18.1 port of Azanor13's original Baubles) Ver baubles-1.10.1-1.18.1
Simply Backpacks - aimplybackpacks-1.18-2.0.1-build.28
Forge 39.0.8

Please provide the version of forge used, and the mod version.

i was not aware baubles had been ported past 1.12, the 1.12 version of backpacks was the last to support baubles cause it stopped being ported.

It looks like its been ported by lazynessmind as "Baubles - Reborn" but does also list Azanor13 as Author. Curseforge link - https://www.curseforge.com/minecraft/mc-mods/baubles-reborn Interface and mod description is 100% the same as original Baubles, so looks to be a direct port.

regardless, the mod supports curios now days, no need to support both api's, and curios is in far more packs then baubles is now days.
