How long is the cable from the LV-transformer to the batbox? The transformer has 1 input and 5 outputs, are you putting power into the proper side? It should be the side with a special texture on it. Also make sure you are sending the power into the correct side on the batbox (any side without the special texture).

Yes, all items can be made using either kind of tin/copper. I havent encountered any problems at least.

Thanks for all the solutions! Im gonna go with the light level plugin first and plug the light gaps in my factory, hopefully that will keep the creepers away. If this fails Ill try the towny plugin Maybe I can set up a high density creeper area inside my friends house while Im at it :DD

I thought that was cumbersome too, I made my own server and disabled spawning of one of the in/copper types there so my world only has one type. Disable it and make a fresh world and you shouldnt get double tin/copper :)

I just finished my sorting machine and it works great, next step was to automate fabrication of advanced alloy and carbon plates. But creepers are spawning in my base, when I hear them "Fssssssst..." its too late, they explode and take with them my machines, pipes, diamond pipe intersections and similar. Im kinda stuck, its very time consuming to progress further and this was sort of my last try. I placed out a bunch of blue torches (monster repel torches) but not even that seems to help. I can play for up to an hour a day so rebuilding my factory whenever a creeper decides to come for a visit is not an option. I have placed tons and tons of torches around but monsters spawn regardless. Mostly its zombies or skeletons that spawn but if they can spawn then maybe next time a creeper will spawn. Is there a way to prevent creepers from spawning inside your base and blowing up? Im assuming that there is a way because its stupid to have your base blow up at random from time to time, that would be bad game design. Please help I dont want to disable creepers or monsters alltogether but I dont really care if I need to cheat or install mods, as long as I can keep them out of my base Im happy. I cba rebuilding basic machines all the time, I want to progress and make my warehouse larger and more efficient :)
