Hi,
Don't hesitate to bump threads, it's fine. Indeed the volume of requests is getting bigger, so you need to shout louder if we skipped your thread
it's not intentional, we just missed it.
If you still have your 5.6 project back up, can you just update PlayMaker to the latest on there and check if the behaviour changes, if not, then the issue is elsewhere.
I am having a hard time figurin out your rig, maybe you could share just your character rig on an empty scene with just a floor and debug it there, pm me with that scene if you can, I'll have a look.
Bye,
Jean
