I have looked and I cannot find the answer, sorry, but can anyone tell me why my ha base will not appear before the new backgrounds when I drag it there? The items all show up but not the base. I have had this issue for quite awhile and it tis making me sad. :( I use chrome, I have cleared cache many times.

If you're layering it correctly, you may want to try resetting your base using this link

That worked. Thank you so very, very much! :)
