Minecraft crashes while i am charging improved vampire swod, holdig shift+right click.

here is the crash report
crash-2020-07-30_12.34.09-server.TXT

This seems like an issue with https://github.com/tterrag1098/Blur
I don't know how Vampirism is involved (besides triggering the crash)

Might have been an issue on our end, not sure why it crashed though.
Let us know if this occurs with Vampirism 1.7+
