pengH 谢谢你发送你的Spine项目! 原因是在一个选择组中仍有对已删除附件的引用。在你的Spine项目中，在分配给 2 键的选择组中仍有对 xiaoyaoxian_35 的引用。如果你按下 Ctrl+2 来重新配置存储在 2 键中的选择组，警告将不再出现。
这个问题在最新的Spine编辑器版本中没有出现，但在3.8.99中，我们意识到对已删除项目的引用仍保留在选择组中。我们对造成的不便表示歉意，但3.8版本已不再进行修复或更新，如果你将来遇到同样的问题，请重新配置你的选择组。
Thank you for sending you Spine project! The cause was that there was still a reference to a deleted attachment in a selection group. In your Spine project, there was still a reference to xiaoyaoxian_35 in the selection group assigned to the 2 key. If you press Ctrl+2 to re-configure the selection group stored in the 2 key, the warning will no longer appear.
This issue does not occur in the latest Spine editor version, but in 3.8.99 we are aware that references to deleted items remain in selection groups. We are sorry for the inconvenience, but 3.8 is no longer being fixed or updated, so if you encounter the same problem in the future, please reconfigure your selection group.
