Crash when using unset leaf on Riftway

[Ilikepinapples]

When using an unset leaf on a riftway the game crashes
steps to reproduce:
Create a riftway.
Click on riftway with a leaf straight from the creative menu - don't rename it.
The game will crash.
This issue is persistent on both versions of the mod (0.0.2 and 0.0.1).

It looks like the mod tries to check data that isn't there and crashes.
