Basic logistics pipes won't connect to a power junction (required for a logistics system to function) in SMP, and placing a basic logistics pipe next to a power junction in SP will crash you. Downgrading to #75 fixed the problem.
On a server I ran the power requirement for Logistic Pipes kept getting "stuck" draining power constantly, even if not connected to a logistics network at all. Breaking the block and replacing it fixed it, but not after however long of constant power draining. The need for power isn't really needed. Once you have that box it's basically all the power you'll ever need, so there's no real cost to running it beyond the starting price and that cost has already been paid for by GregTech's crazy prices for everything. I'd say drop the power need to keep things simple and reduce lag/power usage on the server.
