Heyo,
Found a minor bug with Morph and Astral Sorcery installed.
HOW TO REPRODUCE:

1. Load Minecraft with Astral Sorcery, Morph, and related dependancies
2. /summon and kill a Flare.
3. Morph into a Flare, move around a bit, then morph back into a human.

ISSUE ON MORPH's GITHUB: iChun/Morph#1101

Not something we support.
