Issue description: Builder offset not being affected after changing in the config file. I went into the config file to change the offset maximum to 5000. I am using the FTB Revelation pack, which has the deep dark dimension in it. I built a small base in this dimension to allow me to use a reactor that powers the builder to mine out the whole dimension. I want to minimize moving the reactor and builder setup so I wanted to change the maximum offset and even dimensions size. When I changed it, saved the file and restarted my server. The values that I changed did not have any affect on the builder at all.

Steps to reproduce: Go into config file to change the offset value and dimension size. Check to see if you are now able to increase the size of the builder dimension past max size and offset. Notice it still doesn't allow you to go past the default maximum.

• CompatLayer (only if on Minecraft 1.10 or 1.11):
• McJtyLib: 3.5.4
• RFTools: 7.72

Possibly incompatible mods and versions: The only other mod that isnt listed in the FTB Revelation pack is OptiFine, which I don't think would be an issue in this specific case.
