This is the SlimeVoid version, right? If so, don't install the SlimeVoid Additions addon. It makes clients crash quite randomly when using wireless redstone.
Yeah, I saw that so I was sure not to. But the reason I didn't reply sooner was that my build script fucked up so I had to wait a bit for it to copy the files again. But all seems well. I will push the mod to the 1.5 update and we should be good to it in 1.5. So this and the addons are definitely Accepted.
I added this a while back... Maybe the commit didn't push or something (crappy internet sometimes just freezes )
