Strange issues and server crash when accessing storage network

[TheDeviantCrafter]

I don't quite know how to replicate this, but here's what happened. I dumped a bunch of items into an EZ Storage network. Roughly 14,000 items in total.

Since then, any time I open the network I see a long chain of errors in console. Then I lose the ability to open any GUI, throw items, etc. I suspect the server is frozen.

Then, once I log out, the server crashes.

I think it was related to the RFTools modular storage blocks that were in the system. The issue occured any time they were rendered or extracted.

After extracting items until the server crashed about 5 times, they eventually disappeared from the storage UI and everything started working fine.

I had taken out the storage modules, but they still had quite a bit of NBT data. That may be related. The blocks store information like the owner's UUID, stored RF, and various settings. One block having a kilobyte of NBT data isn't uncommon.

It looks like a Tinkers' tool and an enchanted book also vanished. Maybe the system deleted anything with NBT data.
