It seems that Aether Redux and Mythic Metals are still crashing even after the latest update.

Crash Log: https://pastebin.com/mdT9NjG5

I loaded an installation with only those two mods present to confirm the issue is solely between these two. The ticked entity seems to always be a vanilla mob but alas I don't know if it's this issue is only on my part u-u

Thanks for the crashlog. I think I know where this issue happens. I will close this as a duplicate of #229 and track it there.
