ArithmeticException NAN when changing time scale to high value

luciddream

Hey, when I change the speed of my game at runtime by setting the time scale, I get this error. The time scale is 10.
There is another post that refers to this problem

In Time scale = 1, it happens as well but it is rare

The problem is when I blend idle, walk and run

@luciddream Sorry to hear you're having troubles. Which version of the spine-unity and spine-csharp runtime are you using? Are there any Physics Constraints involved (these might be configured unstable)?

If you're using the latest spine-unity 4.2 package and not using Physics Constraints: Could you please send us a minimal Unity project that still shows this issue? You can send it as a zip package to contact@esotericsoftware.com, briefly mentioning this forum thread URL so that we know the context. Then we can have a look at it.
