在使用Spine 4.2版本时，物理效果在不同界面表现不一致的问题可能与物理约束的设置有关。根据之前的修复记录，4.2.11版本中存在物理约束的默认顺序错误问题，这个问题在后续版本中已经得到修复。建议您确保使用的是最新的4.2.23-beta版本，因为该版本已经修复了一些物理相关的问题。如果问题仍然存在，您可以尝试检查物理约束的设置，或者在Spine编辑器中查看工具提示以获取更多信息。

Correct, the latest 4.2 doesn't have known bugs with physics disappearing.

What do you mean that physics disappears? Your skeleton is shown without any physics at all? Are the physics you want from moving the GameObject of from animations being played? Are you calling Skeleton updateWorldTransform? If so, make sure you are passing Physics.update. If you are handling time passing yourself, you'll also need to call Skeleton update. If you aren't doing those yourself, you can inspect the spine-unity classes to make sure the expected delta time is being passed to Skeleton update, etc.
