In 3.0.6 f1, I get the error
"The animation state CardBack could not be played because it couldn't be found!
Please attach an animation clip with the name 'CardBack' or call this function only for existing animations.
UnityEngine.Animation:Play(String)"
when actually it’s the Target that is missing from my UIPlay Animation. The delightfully snarky "I can't play animations that don't exist" error is rather spoiled by this inaccuracy.
I'm pointing this out in the hope it can be fixed and save someone else wasted time.
(The fact that some targets have randomly gone missing may also be a bug but I can't repeat it as easily.)
