Issue Description:

In testing/trying to brute force replicate a bug in Rftools I broke blood magic (go figure), Tile entities from Rftools crash game to desktop if placed into a mimic block (Honestly, I don't know what I expected...)

Did a further test in my modpack to see if it was all TE's and I narrowed it down to at-least Rftools and Mekanisms TE's doing so, everything else I tested either rendered correctly, invisible or broken textures (Extra utils 2, Forestry, Gendustry, Vanilla, Actuality additions, IC2 and more)

Reporting as an fyi more than anything, its a kinda rare way to crash.

Crash log: http://pastebin.com/b8d3AWxX (only posting one as all the same)

What happens:

Crash to desktop instantly on trying to place Rftools/Mekanism tile entities into mimic blocks

What you expected to happen:

If anything I expected tile entities to be auto-blacklisted/just not work, bit of testing shows me they do work (some have broken textures or invisible but don't crash) but anything Rftools or Mekanism based is insta crash

Steps to reproduce:

1. Get any mimic
2. Place in world
3. Place Rftools or Mekanism tile entity into it
4. Crash to desktop
