I think my previous thread was closed due to me not formatting the question correctly.
Other people on my personal server can link teleporters together without issue, but when I try to link two teleporters it tells me in one line of text that they were successfully linked, then the next line of text says they are unlinked. It is as if I am right clicking twice, but that is not the case and I have confirmed with other tests both in minecraft and out. My friends and I are using exactly the same .jar file, which is vanilla save for IC2 and required mods.
Please help as my friends are teleporting into my house and back and I cannot do the same without asking them to link teleporters for me!
