No, I mean
When I say "server-wide" I mean that every player has experienced the same thing suddenly - every Immersive Cable that was part of a power network disappeared. Every single cable on the entire server is gone. POOF. Everybody's bases are chunk loaded around the clock using Railcraft World Anchors.
Some of my cable runs (in fact most) were very short and didn't cross any chunk boundaries. A lot of my wiring is vertical and doesn't even cross a
block boundary, and those are all gone too. So that doesn't seem to be the answer here. Something else happened. A server crash at a critical moment, perhaps? The sysop mentioned something about if the server crashes during a backup save. Who knows? That's why I'm asking. It's a big task to re-wire an entire base if you're using mostly all Immersive for your power source like some of the guys on our server are.
And while I'm at it... a pat on the back for myself, for being such a neat freak about my wiring that I had no problem figuring it all out. Some guys are pulling their hair out right now, they have no idea which wires were going where. LOL
