There are two different pages on the mod's curseforge website, and I can't find the Mrcrayfish furniture mod compatible with minecraft 1.12.2 on the aternos Server creation site. https://www.curseforge.com/minecraft/mc-mods/mrcrayfish-more-furniture-mod There is no 1.12.2 in this link but https://www.curseforge.com/minecraft/mc-mods/mrcrayfish-furniture-mod/files/3865259 In this link there is version 1.12.2. I can't add your mod for my server because the Aternos website uses a link that is not 1.12.2. I would be happy if you add your mod to the link above for minecraft version 1.12.2.
