Wendo

I doubt it, since it's that the mod has know knowledge of multiple worlds. To fix it you'd need to recode industrialcraft to support multiple worlds

The problem is the way you went about making the new world. EE doesn't support multiple worlds so all the saved data EE has points to your old world. You could try literally renaming the new world so it has the same name as the old world (and change server.properties).

3.0.1 looks good!

I should also mention, you'll find a lot of IC2 things don't work in other worlds, things like the wrench will no longer remove machines etc

Yeah, Multiverse will cause this. What happens is the orientation isn't stored per world, so once you start loading more than one world the orientation is applied to the first world loaded (which won't be "world") and so all of "world"s machine revert to facing the same way

Timer for what... ComputerCraft? Something else?

Maybe waiting more than an hour for a reply would help, we're not all in the same timezone and since a new version has just been released, people are probably working on their own issues. It could be any number of things, how far above the house are these windmills, and how far from them is the batbox. Have you wired into the input side(s) of the batbox or into the output side (the one with the dot). Perhaps if you supplied us with a little more info or a picture we would be able to point you in the right direction

It's buggy though, especially if you have a full inventory. If what you're making will stack with something in a full inventory it causes severe errors in the server console and sometimes doesn't use any mats.

If you run a batch file and "nothing happens" then your windows is completely broken. Something will happen, even if it's just a window flashing up for a second. Without knowing what that window says it's pretty hard to give you any useful instructions other than make sure you have Java 7 installed

They are called energy links, they convert IC power (EU) to BC power (MJ) to run things like quarries directly from MFSU's etc, this is the same thing the electric engines did

Yes, when getting BC power from a block it must go into a wooden conductive pipe first then onto normal conductive pipes

Post pictures, perhaps remove the transformers and add transformer upgrades, likely you either have the transformers around the wrong way or the MFSU's aren't facing the right way or you're using cable with too much loss. Pictures will make diagnosing it simple

You can also use engine generators to get it back to EU, you have some losses but nothing too bad so you would go batbox->energy link->power teleport pipe and on the receiving side power teleport pipe->lv engine generator->batbox->whatever you want to power

Put the config in here and make sure the output is less than 512EU, if it is then nothing will explode http://www.talonfiremage.pwp.blueyonder.co.uk/reactorplanner.html

The chances of his reactor outputting more than 512EU is pretty slim unless he's filling it with uranium and pumping in ice

If it's coming out of an MFSU then an HV cable would push it up to 2048 and blow the glass fibre cable. Either use HV transformers at each end with the cable you have to convert up to 2048 EU on the cable (you'll probably want to use MV and LV at the energy link end to to bring it all the way back down to 32 EU so the energy link doesn't drain the MFSU OR replace all your cable with glass fibre, again you'll want to make sure it's LV by the time you push it into the energy link Your second question was probably simply that the game unloaded the chunk because no one was there. Drop a world anchor there so the chunk stays loaded when no one is there

You've connected the solar panel to the output of the MFSU. Connect it to a different side All power storage units have 5 inputs and one output

That looks like an MFSU to an MFSU, and if you're expecting power to go from right to left then you've connected to the output of the left hand MFSU. A picture (or a couple) of the whole actual setup getting as many directions as you can would be more useful.

The minecraft setup in railcraft can transport power via an MFSU in a cart. If you're talking really long distances I'd think about that. Of course if you're talking relaly long distances just generate it on-site

Is it daytime and not raining? What about if you try a generator? Have you tried putting your power source next to/on top of the MFSU? Is the MFSU facing the right way so that you aren't connecting the panel to the output? A picture would be useful here

The stickies nicely tell you this is because you need Java 7, in fact so would a simple google search of the error :/

You don't need to give it that much memory, not even close for less than 10 people. There is also no reason to start the server on 7GB. With only 8GB of RAM I'd actually be worried you're starving the OS and that's contributing to the issues. All OS's use free memory to cache commonly used files, which makes accessing them much faster. My guess is since your OS can't do this anymore you're seeing the warnings because of what tekkit perceives as slow disk access. Drop it down to something like -Xms 2G and -Xmx 4G and see how you go. The end of stream issues could be related to a plugin, at least that'd be where I'd start, remove all the plugins and see if it works again

Restarting the server has fixed this in the past for me

I'm not talking about your user permissions. Some of the mods have fake users so events can be logged properly. If those users don't have permission to break the blocks a quarry won't work. From the above though it does't look like you have a permissions plugin so unless it's something specific with your setup I've no more ideas

Post a picture of the setup, it could be a setup problem, or a permissions problem if the server owner has added a permissions plugin
