When attacking using Better Combat (specifically attack animations the rotate the player's body to large degrees such as claymores/tridents/spears/hammers) the legs appear the follow the body and cause them to awkwardly lift off of the ground.

The effect isn't as noticeable while moving, but still there. Especially noticeable with the hammer.
I've also seen a couple other reported issues, one also relating to the "stiff legs" issue with Better Combat, and one requesting compatibility with Celestisynth.
Both use the "Player Animator" mod, so I believe it's an issue with that.

I'm not sure if compatibility can be done with this resource pack or if it's an issue that must be fixed on EMF's side, so I'll be reporting this issue on both sides just in case.

I joined the discord for ETF/EMF, and see that some issues related to Better Combat have also been reported there.
If this needs to be closed, feel free. Completely on me for forgetting the check the discord before reporting here.
