HIya, I don't know if you have had this reported, sorry if you have:
I get this error (client side only, crashes client but no errors on server console) when trying to shift -click an item or block (any) into a Destructopack:
mc 1.4.2, forge 6.0.1.350
thanks for the mod
--edit
tried it again with forge 6.0.1.354 and a fresh download as per the op. same error.
I get this when attempting to link a portable teleporter to a powered teleporter in ssp.

probably because 1.107 
hey just got your mod installed (latest version as of this post)
first lemme say i really like the idea / texture, but
i can't seem to destroy them, as
left clicking seems to also open the gui
thanks
Nice thread 
Wish I'd found this 2 days ago XD
I too was very happy when I figured out that the textures were side AND state specific.
Probably worth mentioning that : the L and R sides should swapped if you are facing the block.
and that Advanced machines and Generators follow the same format too.
cheers
