I don't know if anyone else is affected by this, but for some reason I can't switch on a nano saber. I right click to switch it on, and then it switches itself off again shortly afterwards. The amount of time it stays on for differs each time, but the result is always the same. Does anyone else know about this? If so, is there a workaround? I should add I only noticed this since the latest update (on the mindcrack pack).
