Hi,
I have been working with a friend to create a modded server using forge. I have two servers, one on 1.12.2 and 1.14.4. I can use all mods on a single player map, however on multiplayer, i have watched many videos and gone through different guides to figure out my predicament. I have a server from apex which is not a vanilla server ( 3G and 2G both dedicated). Mods such as Biome O Plenty and midnight do not work even though i can see them in creative mode inventory (can't be placed or spawned). other mods that give me a map or tweak some characters work though.
