Just tried the v2.0 Snapshot, as suggested by someone in the comments on the CurseForge page (with EMF v 1.1.0, ETF 4.6.1 and player animation lib 1.0.2 rc1) and found two bugs right away:

• When crouching, my character suddenly tilts to the side. Oddly, this goes away if I hide the UI with F1, but as soon as I bring the UI back, my character just tilts again

• The standard walking animation is a little juddery. It's almost as if the animation cycle can't quite decide when it needs to activate so there's like a little "shuffle" of animation whenever I stop or start moving. (Not as much of an issue as the first one)
