Description of Problem:
Well, my friend and I have been playing on our tekkit classic multiplayer world for quite some time. We have several power flowers, teraformers, and lots of stacks of diamonds. Anyway, I recently made a sorting system, it is a little laggy but nothing my server couldn't handle. I didn't have any problems with it. Anyway, so one day when I joined, I got an EXTRAORDINARY amount of lag, that didn't happen when I wasn't on the server. I thought it was my tekkit, so I reset the launcher, nothing. I reset the server, nothing. I try importing the world with multiverse, it works fine because I'm at the spawn thousands of blocks away from my build. As I make my way back, it gets laggier and laggier. I'm about 10 blocks away now and the extreme lag is starting. It's pretty clear that it's the world by now, and something near our builds. I looked in the folder, there were some weird files. Like even when I delete it, a file called DIMnull is generated. In DIMnull, RedstoneEther is generated.
In RedstoneEthel, fmap.dat, node1.dat, and node2.dat is there. I think that something with DIMnull is causing this problem because all the other weird files I deleted (ones that weren't in a normal world's folder) don't get regenerated whenever I run it. Even on singleplayer. I HAVE NO IDEA what this is! Anyone that has help please respond!
