I'm running a forge server, and whenever someone joins, it's fine for a short while and then the client crashes (the server stays fine) The server was running fine, then I added mods (ChickenChunks, ComputerCraft, Foundry, netherportalfix, SimpleQuarry, SoulShards, Torcherino) and then this problem started happening. The problem persists if all the new mods are removed.
