The StructureComponent GenericVillagePiece can store null under the key RcInstDat if writeStructureToNBT is called before addComponentParts. This is causing an issue with SpongeForge, which expects all NBTTagCompound to have non-null values.
If you wouldn't mind fixing this, the Sponge team would greatly appreciate it.
