I have just set up a working and lighter version of a Monster server for some friends with lower spec PCs; mods I have disabled include ATG, Highlands, Mariculture, Biomes 'O' Plenty, the associated Bibliowoods plugins for those mods which are now disabled, IC2 nuclear control, MMMPowersuits, Powersuit Addons, amongst others. I have also enabled Ars Magica 2 into the modpack. Now, when my friends try to join, a few of the times they get a disconnect.overflow error. Any ideas?
