Issue description:

Cable is causing a server crash

What happens:

Server crashes on log in or single player client crashes on block break

What you expected to happen:

Not that ^

Steps to reproduce:

¯_(ツ)_/¯

Version (Make sure you are on the latest version before reporting):

• Minecraft: 1.10.2
• Forge: FTBserver-1.10.2-12.18.3.2215-universal
• Refined Storage: refinedstorage-1.2.18

Does this issue occur on a server? [yes/no]
yes

If a (crash)log is relevant for this issue, link it here:

crash-2017-01-25_23.32.00-server.txt

Why are you saying that you are on Refined Storage 1.2.18 while the crashlog says you're on 1.2.17?

UCHIJAAAA refinedstorage{1.2.17} [Refined Storage] (refinedstorage-1.2.17.jar)

Update to 1.2.18, it fixed the issue.

Sorry the crash report is from Refined Storage 1.2.17 but it is also occurring on 1.2.18... this bug is still very much valid.

@raoulvdberge crash-2017-01-26_23.26.37-server.txt

That is another issue.

¯_(ツ)_/¯ crash reports look identical to me...

Nope, it occurs in another place. So it's an other issue.

It seem to have something to do with a cable BEFORE a cable connected to crafters, but I'd take the reports word for it not mine ;)

Even though they look identical (same error) they are ocurring at another place in the code. That's why it's important to absolutely include the crashlog from the latest version, not an older one.

yeah I'm not sure why I attached the 1.2.17 one, that's my bad... hopefully you can get it sorted, I was a hardcore AE fan and not immediately sold on RS, but tbh I love it man. Keep up the good work.

Thank you, shouldn't be hard to fix. Expect a release this weekend.
