After writing nbt data to a schematic using the schematic table, deploying it causes the client to crash. This happened in 0.3.1 and 0.3.1a and not in 0.3e.

In the crash report, Mekanism is loaded in addition to Create.

In another case, I tried adding Quark or Immersive Engineering, but it didn't crash.

Here is crash report
