Overlays Not Removing in Developer Help

I had this problem a long while back, I can't remember how to fix it though.

My overlays are unremovable because saving melds them into the icon, how is this fixed? I forget.

Saving doesn't melt them on. Ex; for an Unequip verb, when you remove the path or file of the overlays it goes off. (For me it does o.o). Another way would be to save the mobs original icon.
<dm>
mob/var/origicon
mob/verb/Add_Overlay()
usr.origicon=usr.icon
usr.overlays+='overlay.dmi'
mob/verb/Delete_Overlay()
usr.icon=usr.origicon
//or
usr.overlays-='overlay.dmi'

Of course, adding and removing overlays with a special verb would be ridiculous. Doing so via a proc, where you'd be using src instead of usr, would not be.

If you want to remove all the overlays you should try:
 for(var/overlay in src.overlays)
  src.overlays-=overlay

I don't think you can loop through overlays like that. To get rid of all of the overlays you can set src.overlays to null.

Ive tried the loop, it seems to be removing them in my test. src.overlays = null sometimes doesnt remove the overlays (according to my games). Your overlays are a list, and it goes into that list and takes each overlay, so it should work.

atom
    var
        list/Overlays=list()
        list/Underlays=list()

    proc
        update()
            updateOverlays()
            updateUnderlays()
        updateOverlays()
            overlays=null
            for(var/i in Overlays)
                overlays+=i
        updateUnderlays()
            underlays=null
            for(var/i in Underlays)
                underlays+=i
    New(){..(); update()}
    Del(){overlays=null; underlays=null; ..()}

It's fixed like that. Instead of adding objects to the overlays/underlays list, add them to the Overlays/Underlays list then call the corresponding updating procedure.

What about using overlays.Cut()?

I know, but it's still goofy to give a verb example in a situation that clearly calls for a proc.
