XD So, I'm not the only one that got guff from grass with those things. Oh, and a single block of leaves.Sounds pretty much life what I've done, but no explosions or any other reaction. Beginning to wonder if it's a mod interaction issue, or maybe because I'm in an RFTools dimension. Guess I'll just continue looking for things to try.
-- Edit --
Seems a single piece of grass was defeating me. Ignore my previous whining
Also, for now, I have knuckled under and used regular repeaters for power. The loss on the broadcaster is far, far too high to be useful in all but the most minor of capacities. I'll probably re-visit them once I can turbo-charge them and maybe I figure out if this "anti-attenuation gem" does what I think it does. Good news is, I've manged to progress quite far after doing that, and am just about to hit the dimension. Hopefully, it doesn't crash on entering like it did in earlier versions of Infinity.
