Lightning Summoner bug? (MPS)

[Rasral]

Hey guys, well i've managed to find and reproduce anoher MPS bug in Tekkit. Was wondering if you guys had any help or sugestions.

 

Basically, if I install the Lightning Summoner i can select it like a usual tool and everything, but it refuses to work. I cannot summon lightning. If i then go to the Tinker Table and "Salvage" the Lightning Summoner, it uninstalls it and places most of the parts in my bag. However, the Lightning Summoner is still selected on my Powerfist..and thjis time it works. If i disconnect or change tools it vanishes. It does this every time without fail.
