Notes

Probably best NOT to FREEZE values in the editor.
Do not change values in the editor unless they are showing values in editor that match your character stats or whatever it is you are trying to modify.
Some values will not show in the editor until you can access the MENU to look at the character stats.

Credits:
For Player Progression values to show, press TAB, then click on the character you wish to see values for.
