So, looking at the log it suggests that Reborn Storage is trying to recognize a Refined Storage cable as part of its multiblock crafter. Which is silly. My first suggestion would be to look for updates to Refined Storage and Reborn Storage.
Edit: poked around RebornStorage's issue tracker page, found a report with this exact issue that was closed with the December 6th release of RebornStorage. This update made it into the Direwolf20 pack in version 1.4.0 of the pack.
