PCS:Cannot load save that depends on unavailable content
A brownish extension protrudes out of NPCs and/or items.
Causes and Solutions
This may happen if a save file depends on information in a plugin that is not active in your load order. It is more likely that this will result from trying to remove a master file than a regular plugin. Another common situation is that the PC depends on unavailable hair, eyes or race from an unloaded mod.
Solution #1: See Updating Saves. In uncommon, unfortunate cases the save file cannot be salvaged without installing the referenced dependencies.
