After a couple of minutes in another Dimension i couldn´t pull out items from my Wireless Grid (The controller is in the overworld and its loaded), but a normal crafting Grid works.
I havent tested it in the newest version 0.91 because it says nothing about that in the changelog.

• Minecraft: 1.10.2
• Forge: Don´t know
• Refined Storage: refinedstorage-0.9

0.9.2 on Curse (as soon as it's accepted) should fix this issue

Thanks :)
