qq674011023 Sorry for the delay in getting back to you! There are a number of possible causes for this to happen, as there have been many changes between 3.8 and 4.2, and it is not possible to determine the cause just from that screenshot. For example, between 3.8 and 4.2, there have been fixes regarding the specifications for rotation inheritance and the constraints specifications.
In many cases, automatic resolution is not possible and must be corrected manually. If you do not know how to fix it, or if you want to know the specific cause, please send us via email the Spine project where the problem occurs: contact@esotericsoftware.com
Please include the URL of this forum thread in the email so we know the context. Then we can take a look at what's wrong.
