Crash on placing rusted chain in arrangement GUI

[Forecaster]

I placed a small rusted chain in the decoration/ground cover slot in the arrangement GUI and got this crash-to-desktop: http://hastebin.com/ocakabakal.profile

Attempting to open the world triggers the crash again.

Awesome, a garden proxy inside a garden proxy. Gardenception.

I'll post a fix tonight. If you want to fix your world before then, you'll need to do some digging with NBTExplorer or related.

Nah, it was just a throwaway world, it's fine.
