It is the FZ router from Factorization and NO it is not in AS. He must have added it.
Please, if your are going to post pics with solutions you have come up for a quest that involve additional mods that are not in the pack by default, you should explain that you have modified the pack so people that read this forum don't go on wild goose chases trying to figure out what you did...
I mention Factorization in the post. If people don't know how to tell what mods are in the pack they're playing that is their problem, not mine. The router isn't a wild-goose. If they go chasing after it they will find it in modded minecraft sooner or later. You'll notice I said it was my favorite machine in modded minecraft, not Agrarian Skies. I don't really think of AS as a beginner-level pack. I'm assuming most of the people who play it and post about it have some familiarity with modded minecraft.
But hey, god forbid anybody should be confronted with something new. Wouldn't want that to happen. The confusion could cause worldwide panic, dogs and cats living together, mass hysteria.
So please, don't assume people are confused. Don't assume they will be confused. Don't assume they'll do everything other than simply ask about whatever is in question. If they decide to go on a wild-goose chase instead of simply asking, whose fault is that?
As far as "cheating" goes, I'm using routers in roles that could be handled with TE ducts or AE networks. Less lag, no million cobblestone all over the place when I decide to wrench the wrong duct, cleaner builds. If that is cheating then I'm a cheater who will continue to look for new ways to cheat. The game simply isn't fun when the load is so bad that it is backtracking every other block you break. Been there three times with itemducts in AS.
