Please excuse me if I am misunderstanding some of the interactions between these mods a little but..

I have connected up the bridge and bridge pipe and can see the contents of LP in AE2. Everything there is listed as a craft, which I presume is your way of modelling the interaction, however it might also be the source of something wrong..

I have a tiny AE2 system, and a huge LP system.

What IS working,,
If I have 0 of an item in LP, but have a craft recipe for it, the AE2 system invokes the LP craft and the item appears in AE2. Awesome!

What isn't working

AE2 request from LP

However, if I try and request something that is in stock in LP using AE2, it is listed as a craft. The craft screen pops up as a Simulation, and does not allow the request.

Here, sticks are in stock in the LP system (in a void-overflow barrel with a Provider module).

LP Request from AE2

I put an item I know I only have one of into my AE2 system. I can see this item in my LP gui, but it won't let me request it (LP states it is missing)

Am I getting something wrong?

The pattern seems to be that I can invoke all crafts, but if an item is already existing in LP (whether it has a craft pattern or not), AE2 cannot request it.

I am in 2.0.9 of the FTB Interactions pack, but with a manually upgraded Logistics Bridge mod (latest). I can paste more versions if that is helpful.
