Atlasses not being deleted

When i open atlases there are tons of sprites that should not be there since i have already deleted the objects in the game.
I tried deleting everything on the game (i made a copy of course), and tried optimising atlases again and they are still there.
So i guess it´s a bug. Unless somebody had the same issue and managed to solve it. Any help would be really appreciated.

 

you can select that art and manually delete if need be

 

tried, but this message appears: "The sprite is in use by some objects, so it cannot be deleted"

 

Have you tried Remove Unused Image I fr tools menu and also Optimize on the bottom right on the Assets window (Atlases menu from View, not sure why the window called differently than the menu calls this)

 

I have tried, clearing images says 0 images removed lol
But they are still in atlases

 

Maybe some objects are still using them...

 

that´s what BB says.. but i tried deleting completely everything and did it again but still did not work... so is it a bug?

 

I doubt but if you have a suspicion you can contact to BB Tech Support...

Before that check all objects on the left hand side, write down which objects are not used by those, then check background and buttons and actions and and whatever you use. Tedious job i know but otherwise how would you figure it out...
