It's shapeless familiar. I actually was lucky enough to be playing around with a different character right after adding it so I know 100% that's the problem. I even made a new character in the following order . . .

1) Arcanist + archetypes.
2) Familiar + Archetypes.
3) Levels - 7, improved familiar - Dragon: Faerie.
4) Save, reload, no issues.
5) Add shapeless familiar and select cat save/reload and issues.

However deleting it doesn't stop the error messages so I'm just trying to work out what polyform is as every one of those error messages tracks back to that.

To be even more specific I'm 90% sure its some interaction between the races and the issues only occur after selecting cat in the change shape option for the familiar. See the two attached por's where that's the only difference. It also unselects the option when saving and reloading the portfolio.

Looking at the race - racial special - change shape (raChangesh) there is a gizmo - entity unique id "polyform" bootstraped to damage reduction but I'm not sure where I'd find the polyform its referencing or if that is the issue.
