Hey guys.
I have a server host running with Tekkit 1.18 and for some reason, when I run around, the world stops loading. The way I notice it first is that I kind of "hang" in the air for a nanosecond and then nothing seems to be wrong. I can move around and mobs also move around, however if I try to break a block, the block breaks but no block is on the ground. Also, if I run a little further, there is no more world, just void. I have also tried to battle mobs when this happens, and it seems to be a gigantic lag. I have gotten blown up by creeper a couple of times, and im still alive after im dead (if that makes any sense), I can still move around, however mobs no longer react to me.
If we wind back to where I break a block and the block doesnt show up, if I relog at that point, then I end up at the location where I was hanging in the air for that nanosecond. And breaking blocks work again and the world loads and everything is fine, but a minute or two later, the same thing happens again.
The Hexxit server, whenever I hang in the air there, it tells me I moved wrongly in the console. This doesnt happen on the Tekkit server.
I have tried to figure out what is causing this for several hours now and have not come up with anything. So far I have tested a few things.
1. Vanilla Minecraft works.
2. Bukkit Minecraft works.
3. Tekkit and Hexxit has the problem described above. Tried a professional host, and also tried running a server on my second computer (which is good enough, 16gb ram, quad core 3ghz, ssd etc).
4. Admin from my professional host ran around on the Tekkit server and didnt seem to have the problem that I have with it. He also restarted it, reinstalled it, looked through logs etc etc, but found nothing wrong.
Btw, both servers that I tested was nowhere near running out of resources. The servers were barely used.
I also tried to reinstall Tekkit btw, from my gaming ssd to my OS ssd but no change. Also tried runnning with or without Optifine, no change, also my network is 60/60Mbit Fiber and was only used on Tekkit (One of the servers was a LAN server anyway).
OS is 64bit Windows 7, using Java 1.7.0_25, 64bit.
I dont know what else to include, there are no errors in the logs.
