实测4.2和4.1有这个问题，4.0以及3.8大概率也有
某个网格的权重顺序在导出为：
在导出界面勾选“非必要数据”和“优质打印”导出json后，再将json导入spine后，会发现权重顺序变为：
而且不止这一个网格，几乎所有网格的权重顺序都会被打乱，这个问题对于制作伪3D效果来说是灾难的，除非始终使用同一个版本，不通过json转换版本的方式使用新版本的功能。
导出的json再次导入spine，会发现所有网格的权重顺序被打乱
krammor The issue you describe is indeed reproducible, but not only that, there is data that is not exported even if the non-essential data is checked (for example, the stored selection group will be lost). Therefore, the first thing I would like to mention is that we recommend keeping the original Spine project.
However, it is quite possible to re-import and upgrade skeleton data, so I have created an issue ticket to include the order of the bones in the Weights view in the exported skeleton data in a future update: EsotericSoftware/spine-editor862
