I have an annoying problem with furniture on graal level editor that I need some help with . What's happened is that some furniture (or "images") that I place in the level are ok, but some images vanish and turn into NPC's and have to be reloaded in order to be seen in play mode if the graal editor is restarted. This has caused some frustration as I'm clueless as to why this happens.

p.s: All the furniture/images are taken from the Era PC server through walking around and letting them download into my graal image folder.

Thanks for any help in advance
