Hi,
I don't know exactly if this error belongs to RFTools or not, because it first said :
[08:32:21] [Netty Client IO #2/INFO] [PortalGun/]: [4.0.0-beta-5] Failed to restore setting, probably due to unsuccessful connection to a server.
[08:32:21] [Netty Client IO #2/INFO] [GraviGun/]: [4.0.0-beta] Failed to restore setting, probably due to unsuccessful connection to a server.
but then it say:
[08:32:21] [Netty Client IO #2/INFO] [mcjty.rftools.RFTools/]: Disconnect from server: Unregistering RFTools dimensions
hope you can help me...
If you need the full Client log, just let me know.

This is not an RFTools issue as far as I can see.
