Issue description:
NPE after I tried to open the quarry card GUI from within Builder

This has only happened once so far. It's 2am and the game takes 10 mins to boot up so I'll check again in the morning. Just wanted to get stuff down for posterity.

Steps to reproduce:

1. Place a Builder
2. Shift-click a Clearing Fortune Quarry card on the builder
3. Select two blocks at opposite corners of a single chunk, about 10 z-axis apart
4. Right-click install to the builder
5. Open Builder GUI, turn on preview
6. Exit builder and check the preview is good
7. Reopen Builder GUI and click "Open card GUI"
8. Game freezes with eventual crash.

Closing this as I've re-posted to the new tracker.

I can verify that it also happens in a stripped down instance with just the above, plus JEI and Powah.
