Hi Chad,
Typical questions that comes to mind: From the start with R17 or after a specific update; Are you on the newest update? I guess the support has perhaps some other ideas!
Nothing comes up when I check the “usual suspects” ;o)
If you have a scene where it does this, please without anything else in the scene send it to the support, or share it here for a quick inspection ;o)
Just a wild guess, if you have a scene with this behavior, is the MoGraph cache helping here?
Sorry, that I couldn’t help more.
All the best
