I'm using the Seablock 3.5 pack with factorio 0.17.56 and clicking on any item nothing happens. .An with .58 FNEI crashes and my save wouldn't load. Haven't tried FNEI with a vanila setup with 17.58. If I get time later I will.
The mod ceased to work around two factorio betas ago. My guess is that they changed something the mod used and now it wont work. I hope the glorious creator of this mod will post an update soon because playing with bob's mod in mid game recipes tend to get crazy without FNEI to discover how to produce all the necesary things.
