Hello there!

Blocks / Items involved:

• Schematicannon ( Mod: Create)
• Schematic Table ( Mod: Create)
• Empty Schematic ( Mod: Create)
• Aurora Crystal Block (Mod: BetterEnd Forge)
• Gunpowder (Mod: Vanilla Minecraft)
• Oak Chest (Mod: Vanilla Minecraft)

I made a spiral tower that I wanted to use Aurora Crystal Blocks.
Made it in creative, made a schematic of it. Went to build it in a multiplayer server.
Found a chunk of space to place the new tower. Cleared it. Setup the cannon and its needed items a few tiles away.
Told teh cannon to build. I ended up crashing for a rendering issue.
Relaunched the game, tried to join server again, and promptly crashed again.
I had to have a buddy remove the cannon before I could log on with out crashing again.

Like a good cadet, I tried again, making the tower taller. And promptly crashed upon the cannon activating.

To Reproduce Issue:

1. Clear area for building to be built by Schematicannon.
2. Use Aurora Crystal Blocks in said building blueprint.
3. Prep Schematicannon to build it.
4. Tell it to run the building project.
5. Crash.
