crash report: https://pastebin.ubuntu.com/p/tWmmmtf7BV/
As IAF updated, the file name "FrozenEntityProperties" has changed to "FrozenProperties".
I just crashed when I attack a monster with an ice dragonsteel weapon.

Sorry I'm not sure whether or not other file name has changed.

Fixed in version 1.1.0 but curseforge has to approve it first
