Ive tried all the ways to remove a map revealer but it isn't working at all. Can someone tell me a trigger/way to remove one?

Remove all map revealers for that player.
You cannot remove them at a location, it is the limits for Staredit.
oh yea, remove them all then recreate them. Thanks Yoshi!
Its the only way. Sorry man. There are sacrifices when you're a mapper

Oh yea i need to say thanks again. I've really tried to get rid of them. Doesn't matter how. Man, this really is gonna improve my maps.
I thought you could give certain map revealers to another player? Then you just change them back when need be...But maybe not...
