I did a single player world swap with my friend (seeing as he's going on holiday for a week) as me and my mates wanted to continue playing on the server, when i pasted the world into my folder however, it gave me all of his items in his inventory and i lost mine... anyway to fix this?

Restricted Items: Matter Cannon - Applied Energistics - Protection bypass. Needlegun - MineFactory Reloaded - Protection bypass. SPAMR Launcher - MineFactory Reloaded - Protection bypass. Sacred Rubber Sapling - MineFactory Reloaded - A huge tree, once placed it takes space to up to 4 regions bypassing protection in the process and causing very low fps to clients.

You can build towns on the main world, moon and mars, we don't know how stable the last 2 are so the main world is the safest for base building. Up to date restricted list can also be found >here.

Now some pictures with our Tekkit server:

In the past disapears the sounds from all technic launcher packs. for some packs are founded old backups with sound. the reason is: mojang removed all sound files.. they stopped the support for it. but now i founded also an old backup for tekkit lite and would like to share it with you guys. its working!
here the link:
http://www.mediafire.com/file/lipma9zmal6rl8p/tekkitlite-resources.zip/file
download it and navigate to AppData/Roaming/.technic/modpacks/tekkitlite/ressources and unzip there the file. All sounds will instantly come back!
i hope you enjoy

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!
