Summary of the problem Morph Crash trying to load Nether -> Overworld

Pack Version 1.9.0

What is the bug? Cross-posted from iChun's github, reposting it here in case it helps anyone:

I've been playing Direwolf20 with my girlfriend for a couple weeks now. I had been making several trips to and from the nether with no issue. On one of the trips back, Minecraft hangs for a good minute, and then crashes with the following error:

I have made several trips since, so I don't know what caused the crash, but I wanted to post it here in case the author/developer(s) saw something important.

Mod & Version Morph (suspected), 7.1.2

Known Fix n/a

Addendum: before the crash, the other player listed, Coffeefox, reported that she could not see me at all, I was invisible no matter what I tried. After I loaded back in from the crash, she was able to see me.
