Description of the problem

How to reproduce:

1. Use a tool with Silk Touch to harvest a Forestry Mod's leaf block.
2. Pick it up, and then open the Inventory.
3. Game crashes.
4. Every time the Inventory is opened, game crashes.

I do not know what happened, so I decided to turn to you dear devs.
I will post the same issue to Forestry's GitHub.

Looks forward to your reply!
Thanks in advance!

This is a non ccl issue, ccl just caught forestrys model throwing an exception and decided to enhance the log output. Purely as a work around, based on what i see in that crash, there is an experimental config option in ccl you can enable to try and recover the game state after an item crashes rendering.
