Hi! This really troubles me :/ I'm using FTB Infinity Lite 1.10.2 and mekanism pipes for transporting fluids won't connect to any Industrial Craft machines (Pumps, Mass Fabricators, Canning machines, Ore Washing Plants, etc.). ExtraUtils pipes do connect...

Is this a known bug or maybe an intended feature? Thanks!

Okay, so I took a look at IC2 Jenkins builds, and it looks like the've fixed the issue.

Build 154 changes state: Add better support for mods that forget about both IFluidHandlers

So it works now!
