Is there a way to adjust a setting for all existing npc's at the same time? I know you can change your game settings to effect all newly created npc's, but what about pre existing ones? I'm using dnd5e character sheets and I want to set the status bars to bottom overlapping and wanted to know if there was an easier way to do it than just going into each one individually and change it.
Go to your campaign details page, then settings, then "Game Default Settings". Change the bar location to the desired setting. Save.
Next, go into the game, go to your "My Settings" tab, then Miscellaneous, then Apply Default Settings. Checkmark the bar setting, select the layers you want it to take effect on, then hit Apply Settings. Wait for the bar to complete.
Note: this is supposed to affect all tokens in your game, but currently there is a bug where it only affects the page (map) you are currently on. Because of this bug you will have to repeat the above step for each page (map).
