Description of Problem:

Hey, me and a friend of mine have just been playing a game with the two of us, using hamachi, everything was ok, then suddenly she crashed and then whenever she logs back on, it only loads a very small area around the house and if she goes outside it she falls through the world and disconnects, with error message on the server console of "disconnect.overflow" it happend just after i installed the first redpower things if that has anything to do with it and she gets the error message "Internal exception; java.net.SocketTimeoutException; Read timed out"

Found a fix, not sure how to edit the thread title to say so, but i managed to fix it by, im not sure which of the following fixed it, but, what i did was, build a nether portal in the small area that loaded for the person, which connected to the portal in the nether that was previously made by the portal just off from the house, got rid of the following 3 block breakers, a timer, some redpower pnumatic tubes, and the redpower restone tubes, then they came back thru the portal which spat them out at the portal away from the house, and then all was fixed

apprently having red power timers on low second counts cause chunks to fail
