Wecica After hiding the riding, we got the errors below.
Sorry for the troubles! How exactly are you hiding the ride? Could you please share both the code you are using, and from where your code gets called (e.g. from Update(), a callback delegate, etc)? Such an issue typically originates if attachments are disabled at the wrong time in the update cycle.
Also, which version of the spine-unity runtime (name of the unitypackage, also listed in Assets/Spine/version.txt, or alternatively in the Unity Package Manager window) are you using? It looks like you're not using the latest version of either the 4.1 or 4.2-beta runtimes, as the line numbers of your error messages don't fit the code. If you're on 4.1 or 4.2-beta, could you please have a try updating the spine-unity runtime?
