I was trying different ways to see if i could get to the center of the problem and i think i may have found it. I pulled up the technic launcher console and i was looking at it when it was loading me onto the server, when it says "connection lost end of stream", on the console, it says "[INFO] [Galacticraft] Unregistered Dimension: -28" and "[INFO] [Galacticraft] Unregistered Dimension: -29". Now i'm not sure if this is the problem but this is probably as close as i can get to the problem.
