stuck floating in a void when entering the dimension on my server

[bconlon1]

So I'm playing on a 1.12.2 modpack called Chemical Exchange and I added this mod. It works perfectly find in single player but when I try entering the dimension in multiplayer I am jut stuck in a void of nothing unable to move. I can access my inventory find and look around but I can't move, character is invisible, and my hands are in weird places. I've tried a load of stuff but nothing works. In the server log it says something like it failed to load the script or something like that.
