Hi. Thanks for making this very promising mod.
I noticed some problems when using blueprints with power combinators.
1. Settings of some combinators are copied incorrectly. For example one of arithmetic combinators inside the power combinator was set to "each + 0 => each". After placing the blueprint combinator became "each + I ->" (signal I was used in other combinators).
2. After noticing problem 1, I took a blueprint of this new power combinator and placed it. Now bots didn't place the power combinator at all (hidden parts were placed).

If you want I can give you a bug reproduction save file.

EDIT: Well I just tried to do it second time and I cannot, even with the same save file.

Ok, now I get it. All the weird glitches happen because when I paste the blueprint, more than 1 power combinator is placed. If you place the blueprint holding mouse button too long there will be more combinators placed on top of eachother.
Temporary solution is to slow down the game using console command and press mouse button for 1 tick only.

Rotating the blueprints is also bugged.
