Done Antimatter Chemistry server kick me if I try to join due to a multiblock

I have the problem on "Antimatter Chemistry" so when I try to join I get kicked immediately or I am in the hub. But I tried to join with another account this went until the time I ran to the base then I was kicked and have the same problem. The base is at the coordinates x: 3553 z: 1920 y: 110
We do not know exactly what the problem is.
Maybe it is the 4 inactive Fusion recator on top off our base. So could you remove it?

 

The New Fusions reactor cores are build cross Chunk so it could really them as a Multi Structur.

 

I found out the exact Cords. the Center is x:3537, Z:1983 I do not know the higt exatly but if your replace from 110 to 255 evergy think with are I should fix the problem
