Some entities have 26.50 HP (Donkeys, notably). They are shown (incorrectly) as having 53 HP (2x 26.50).

Screenshot below shows the issue: Hwyla is reporting HP on the top left; ToroHealth in bottom-center.

Interesting, what mod is the mule from?

oh, nevermind, lol

I have verified this bug and will have a fix for it in the next release, thanks for letting me know!

This should be fixed in version 1.16.4-*-4
