Editing game and reloading save files.

I've noticed that some things do not update in saved games after the .rpg is edited while some things do. For example, any changes to graphics/maptiles and text boxes will be shown when the save file is reloaded while changes to attacks lists do not.
Is there a list on the wiki or a post already here maybe that indicates what types of things can be changed without forcing the player to restart the game in order to see changes?

Hero attack lists and limited stock in shops are the two big ones. The closest thing we have to a reference for these things is the RSAV file format documentation:
