Markers explode to NaN after simulation

Hi @Thecc, welcome to the forums.

To better understand your situation, a screenshot or video would help a lot. You can paste a screenshot or drag-n-drop a video here to upload it. If not, then opening a new scene and creating something minimal, like a box, and assigning to this to try and record would help clarify whether it is something specific to that one scene or general to Maya and/or Ragdoll.

Until then, to try and debug this on your end, have a look here for some ideas.
