On the latest 1.11.2 version of the mod whenever you connect any type of piping system to the machines for exporting the world/server crashes. It happens with any kind of modded pipe so I'll only give a crash log if needed. It works fine when inputting.

a crashlog is required to know what's going on, without it we don't know what's heapening

Ok here's an example with an ExtraUtils 2 Transfer Node:

If you need a crash log with a different piping system I'll have no problem sending it. Also sorry for being so late.

no need for another crashlog, this one tells exactly what's going on: the way an empty itemstack (so no items in the slot) are represented changed from 1.10 to 1.11 and the old way is still used in that one place of the sonarcore inventory handler

should be a simple fix when @SonarSonic gets arround to it

Looks like that paste disappeared/expired but it's still happening for sure.

@Mohron that's another crash, that's an api issue

Will the 1.11.2 version ever update? You can't have a crash like this for such a long time.

Still happening on my 1.11.2 server.

This is happening on my 1.11.2 Single Player world as well; not trying to be annoying, just updating this thread

... I already posted it.

It's on the 1.12 version as well. );

@EmosewaGamer could you post a crash for 1.12?

#283 has a 1.12.1 crash report relating to this issue

Fixed in dev

Only for 1.12.1 for now. 1.11 maybe later
