Falling through the world on servers

[Butters915]

I know that a few others have reported the problem, but I have not found any solution with me and my friend's world. When we started the world, there were almost no problems with falling through the world or lag or anything. As we progressed, though, this problem got worse and worse, starting with when I died I would fall though the world for 10-20 seconds, and I would spawn back in with little to no problems. This has now gotten to the point where I cannot play on the server because I would be falling through the world and into the void. Once I let it sit for a while and it took almost 30 mins for me to load in, but I was immediately killed, leaving me to fall through the world. We use hamachi to play together and both have pretty mediocre internet, both staying around 6 Mbps on an average day. Also, we both have around 6 gb of ram allocated to technic, so that is not the problem, as we have both tried lowering and increasing ram. Any help would be great!
