Help needed finding and removing missing line texture.

I have a puppet which I was experimenting with adding a custom line texture to, but I changed my mind and reverted to a default texture. As far as I can tell I have replaced all instances of the custom texture, but whenever I import the puppet into a scene I get a colour recovery pop up saying my custom line texture was not found and asking if I want to recover it, which I do not. Is there any quick way to check which elements are using a missing colour or texture so I can fix it without needing to manually check every single drawing swap for every element of the puppet?
