Corrupted Chunk ? - All the Mods 10

Hi

I placed down an "oak sign" from the supplementaries mod in my base and got booted out. Whenever I try to reconnect it says:

Connection Lost
Network Protocol Error

I was forced to respawn at the spawn and I can connect, but upon coming near the home chunks again the disconnect happens.

Thank you
