Version: 3.1.2

OS: Windows Home 7 Premium 64-bit (6.1, Build 7601)

Java Version: Version 7 Update 45

Description of Problem:

So this has me really confused, and I can't find any similar cases through search results.

I was playing on my own server with a couple of people and I went to disconnect. Immediately after it wouldn't let me reconnect (bad login error). I shut down the server and restarted it, still couldn't log in while my friends could. And they noticed that our door which was made of gold plated support frames were glitched. Everything else was perfectly fine, except for those.

After logging in and out of the technic launcher, I was able to get online again and see for myself.

When I logged in the door was invisible, and could only be made visible by opening it. And when closed again the top blocks would be invisible for some reason. And on top of this the blocks are unbreakable, and do not have any fragmenting effect.

I'm new to tekkit so I have no clue how to fix this ha.

Have you tried REPLACING the blocks?

Of course. The blocks still take up space and cannot be walked through.

Okay good. I don't know how many times people never try the obvious solutions but it's been too many.

You think you could send me the map file in a .zip? I might be able to fix it if it's an entity problem (probably is).
