Players on my server (myself included) are getting kicked with the above message. Each time the coordinates point to a Universal Cable.

I've seen other strange bugs involving multiparts from Mekanism like ghost wires appearing in the Twilight Forest or wires being invisible for certain players.

I am using version 7.0.0.87 on a standard Forge server.

Not sure why this would happen, are the versions the same on client and server? Could you pastebin the fml-client-latest.log (and fml-server-latest.log might help as well) to see if we can work this out?

Closing as this is most likely a user-end error, but we will continue to provide support. As @unpairedbracket said, logs should give us a better idea of where the issue is.

Client server versions are the same for everyone connecting. I'll get those being effected to upload their logs.

If I had to take a wild guess I'd say it's probably a mod conflict. For that I'll post a modlist as well.
