Okay, it looks like that error is caused by a block or item ID mismatch between client and server. If it's happening to everyone, I'd suggest reinstalling the server software. You'll want to make sure you back up the world, any configs you really want to keep, and the directory with the alchemy bag, tablet, and Mercurial Eye info if you're using EE.

Try removing the other guy's player.dat file from the server file structure. You may have to give him his items back. Hopefully this is your server.

Assuming you're using 64-bit Windows 7 and 64-bit Java 7: 1) Push [Windows_key]-[Pause/Break] or go to Control Panel > System 2) Click Advanced System Settings on the Left. 3) Go to the Advanced tab and click Environment Variables... at the bottom right. 4) In the System variables box, scroll down to find Path, select it, and click Edit... 5) Under the Variable value, add ";c:\Program Files\Java\jre7\bin" (no quotes) to the end of the line. You may need to change that directory name, so I suggest making sure that directory exists before doing this. It should be the directory with java.exe in it. 6) Use the OK buttons to back all the way out, and close Control Panel.

Indeed you are. Either you don't have Java installed at all, or it's not in the system path variable.

Try the Tekkit Bug Board. Failure to connect can be the result of everything from internet outage, to ip mistype, to active antivirus/firewall, to Hamachi not working correctly, to...well, you get the idea.

Perfectly understood. I was just mentioning my experience. Does anyone, by chance, have a launcher log from such a crash to review for issues?

Did you read the posts before mine? I actually meant that accessing the pipes while jumping or falling is fine, but if you access the pipes while flying, it crashes your client.

Loading a world backup is about the only thing you can do.

Please submit a bug report! :'(

Not of which I am aware.

Gone or invisible? Did someone use /reload on the server? Hint: Don't do that.

Huh, oh well, I just assumed...I guess I have OP on my own server. For some odd reason the teleport pipes my friend placed belong to me.

AVG! Kill it, quick!

Launcher log? Any firewalls/AV software active on your end?

It might have been a lag glitch. Even glass fiber cable, though, has energy losses, starting at 40 blocks long. You may want to put batboxes in there after 30-35 blocks to prevent that loss.

The only thing I can see is that the port forwarding might have been done incorrectly. Have you tried using the external IP from your computer?

Somebody (possibly you) used magnet mode, then shut it off. It seems to be a glitch. The only way to fix it that I've found is either turn magnet mode on and leave it on, or log out and back in with magnet mode off. This bug can also happen just by turning magnet mode on if the server is even somewhat laggy.

Check to make sure you didn't install 32-bit instead of 64-bit Java, then delete redundant versions. Finally, I'd recommend restarting your computer after any Java install or upgrade.

Jumping/falling seems to be fine, it's just flying, with either creative mode or a SWRG (EE flying ring).

Then post a new log.

Post a launcher log, not a Java error log.

That's how it works. Teleport pipes are frequency-dependent, not user-dependent, as far as I know.

Oddly enough, teleport pipes don't crash my users unless they're flying. If they're flying, it will white-screen them every single time.

The plugins folder is there by default. Just drop things into it.

You usually just need to rename tekkit.jar to whatever file name the server host uses...
