Help Obi Bones With Stretch Bones Get NaN Values

[Jawsarn]

As title I'm trying to set up bones to our character, but it seems that at high changes the bones break completley to NaN Values. If I turn stretch bones off, the bones will still break but be in "no active" mode, to show T pose bones transforms.

The only way I've found to get a "completley safe" case is to set up "Use Limits" on the Solver to restrict the simulation area.

Is this a bug? It feels a bit contradictory to the "unconditionally stable" from documentation https://obi.virtualmethodstudio.com/manu...gence.html.

Thanks for input.
