I've been tinkering with forcefields happily on my tekkit server for a while now, and after sealing my tower off from the rest of the world via force fields, I started getting dropped with a "java.io.ioexception: bad packet id 223" message clientside whenever I get close enough to the tower for the chunks it's on to load. Have to delete the player .dat file, or I can't log into the server. It worked fine while I built the tower, and even when I tested everything. Only when I left it running and walked away to clear some ground did it become a problem. Any ideas?
Oh, exact packet ID changes every other time I attempt to log in, more or less.
