谢谢你发送你的Spine项目。我刚刚回复了你的邮件，但不幸的是，我们无法重现你描述的问题。结果的细节已经写在邮件中，请你确认一下好吗？
Thank you for sending your Spine project. I just replied to your email, but unfortunately, we could not reproduce the problem you described. The details of the results are written in the email, so could you please confirm it?
谢谢你的答复。现在我能够重现这个问题了。原因是 "骨骼 "的比例，也就是整个角色的父骨骼，在动画的第一帧被设置为X:0 / Y:0。如果该值被设置为0，就会出现计算问题。请输入一个接近但不等于0的值，如0.001。
Thank you for your reply. Now I am able to reproduce the issue. The cause is that the scale of the "bone", which is the parent bone of the whole character, is set X:0 / Y:0 at the first frame of the animation. If the value is set to 0, calculation problems will occur. Please enter a value close to but not equal to 0, such as 0.001.
