Issue Description:

Server just randomly crashes with exception, see crashlog below.

Steps to reproduce the issue: (If it's easily reproducible.)

The server seemed to crash randomly, might have to do something with sapling growth, might have something to do with Restricted Saplings?

Extra Information:

Chrashlog

Fixed in a6431cf and will be in the next snapshot release.

Welll, from the description of Restricted Saplings: "When a sapling is about to grow into a tree (from nature, or from bonemeal, or any source) it first checks the biome. If the sapling is growing in a biome that does not natively spawn those trees, the growth is blocked, and it is turned into a Dead Bush."

Not sure what exactly the chain of events is in this case, but maybe that's where that comes from?

Hmm, I've been unable to reproduce this, bonemealing many combinations of saplings in various biomes, and each time the sapling just turns into a dead bush and drops the sapling that was planted. I even tried bonemealing the dead bush - still no crash.

I'll still put the check in to make sure we're dealing with a proper sapling, so at least the random crash should stop happening.

Uhh.. why is a dead bush triggering a SaplingGrowTreeEvent? WTH Forge.

Need to insert a check for this here, and return. Is there more than just a dead bush non-sapling that can trigger this event?
