Just spent a week or so with friends on a server with Unstable. Lot's of great stuff, but, the inevitable crash happened. Ours was caused when I made Enderchests and Endertanks and put them in the ME. Up to then game play and mods were pretty great. MIssed a few mods from Monster such as Rotarycraft and IC2, but otherwise it was a lot of fun exploring new mods and figuring out workarounds to old standby's. Flux infused armor and bow was pretty cool.
