Tekkit Server crashing when joining?

[XmanyX]

Hi, recently I have got a problem with my server;

I was busy on some machines, and out of the sudden my Tekkit server crashed. Now, that happens multiple times, and restarting it would be enough to fix it. Until now.

When I restart the server, everyone can join and it works fine. But when I join ( I host the server on the same laptop I play Tekkit. Does that make a difference? ) the Tekkit server crashes. It gives this error:

Now I don't understand a thing about this, but many of you do. Could someone help me? Thanks in advance.

Ok.. Update to make things a bit weird;

I figured it was because my player file was corrupted, so I deleted my player.dat from the server and rejoined. It worked. My server didn't crash. But when I flew to my house, the chunk loading stopped and the server crashed.. again. Now I'm back to where I started. So, if I'm thinking right, the place/chunk where my house is is corrupted or something. Does anyone know how to fix it?

Dunno if it matters, but the crashing started when I pulled a lever which started two machines.. I'll explain with this:

[R] = Rotary Macerator

[E] = Redstone Engine

[L1] = Lever I pulled on

[L2] = Lever that's off. I pulled this one after L1.

[R]

[L1][E]

.....[L2]

This means, I first pulled L1, starting the redstone engine and the rotary macerator. When I pulled L2, the crashing started.. I don't know, maybe it's an inception of both levers on the engine?
