[Many Problems [Server Crashes]]

Apply the ic2 advanced machines fix found in the server op shop thread about 3.1.3 fixes. I don't remember the name.

[Tekkit 3.1.3 IC2 Nuclear Control Mod errors/crashing server]

tekkitopotamus's profile fixes the problems?

[Tekkit 3.1.3 IC2 Energy Link warnings]

Is this a small server? If so, try breaking and replacing all the energy links. I would use MCEdit unless you load the world in between the removing and re-adding.

[Tekkit Client crashes when on server when activating EE rings]

Can you send the client log?

[My server crashed because of this. Can someone explain what it means?]

I have responded to many similar problems in the bug reports thread. Add it there.

[Crash after Mojang loading screen - Slot 241 already occupied by....]

Good to know. Thanks

[Since update to 3.1.3 i cant start Server With the Same Map]

The server you have has disabled buildcraft and advanced machines because they are bugged and do dont work without patches.

[Since update to 3.1.3 i cant start Server With the Same Map]

No other way to fix it other than backdating.

[Crash after Mojang loading screen - Slot 241 already occupied by....]

That will not let you on most tekkit servers though, right?

[Tekkit 3.1.3 IC2 Nuclear Control Mod errors/crashing server]

Again, update to IC2 Nuclear control 1.1.11 for client and server for 3.1.3 only, not 3.1.2

[Unknown crash Tekkit server 3.1.3]

Remove .techniclauncher/tekkit/mods/IC2NuclearControl_client_v1.1.10b.zip and add the file from the post above labeled client. The .techniclauncher folder is in whatever the .minecraft is on your OS.

[No Join]

This may have been the worst bug report I have ever heard. Please post the error log from techniclauncher/logs/launcher_0.log. Also, what server are you joining? Do you have a firewall? Are you on the right version of tekkit? Do they have other mods? All the information you have is what you need to put.

[Placing thermal monitor crashed my server]

Update to Ic2 nuclear control 1.1.11 for client and server

[One acount doesn't work]

I had the same thing with nickolite ore

[Tekkit 3.1.3 IC2 Energy Link warnings]

Does the rest of powerconverters and buildcraft work?

[Server Disconnect: Black screen->White screen->Disconnect, no posted solutions work]

Get the logs from techniclauncher/logs/launcher_0.log

[Tekkit Client crashes when on server when activating EE rings]

I can't reproduce this. Try checking techniclauncher/logs/launcher_0.log for the error.

[Tekkit 3.1.3 IC2 Nuclear Control Mod errors/crashing server]

Update to IC2 Nuclear control 1.1.11 for client and server

[Buildcraft Pipes and Steam Engines crashing server, Possibly more]

Replace the buildcraft/api in the railcraft zip with the one in the buildcraft core zip.

[java.lang.NoSuchMethodError: buildcraft.api.PowerProvider.receiveEnergy(I)V]

Just do the instructions I posted earlier. They work on Mac and PC

[One acount doesn't work]

Try moving his/her player file in the server to another location and spawn in what he/her had

["There is no item called ###" HELP MEEE :(]

Some tekkit items aren't in creative. If you can't spawn them from nei the make sure you're op and check if you have a plugin modifying the give command. Also make sure the server is actually a tekkit server.

[Crash after Mojang loading screen - Slot 241 already occupied by....]

Try deleting techniclauncher/tekkit to reinstall tekkit. You can keep saves and texturepacks if you want.

[java.lang.NoSuchMethodError: buildcraft.api.PowerProvider.receiveEnergy(I)V]

Yeah, I'm on a mac, so there is no similar program that I have found.

[Tekkit crashes everytime I go to a certain part of the map!]

No Problem.
