I'm in the All the Mods 7 Sky pack. Although I'm not sure how that could interfere, I know it's possible. I'm hoping at the least I can get some help tracking down the issue if it is on my end.

Anyway, I've tried hooking it up directly to a Refined Storage network with an importer and an external storage interface, as well as trying to hook Pipez' item pipe and Mekanism's logistical transporter, and nothing has shown to be able to interact with a dank's storage, on any side of the dock.

confirmed, it needs an iitemhandler capability attached

For some reason, RS importers still can't access. Tested with 4.1. External Storages can, though.
