I just downloaded a mod that I wish to play with my friends, so I start a forge server and put all the mods in it. All of the mods run smoothly but one of it can't show all the items and the mod have a special biomes, the server can generate but the mob spawning in that area also not working.
Therefore, I just try to install the "broken" mod to find out is it the problem that the mod is crashing with each other. It also don't work.
Then, I reinstall the server and my game to an older forge version. It don't work, too.
So I want to find anyone know what happen and can it solve or I did something wrong?
ps. It work perfectly when playing single player with all mods in it.
