I've noticed that in the main game (first and second quests), when you push one of the 4 pushable Heavy blocks in the overworld (and thus triggering the warp ring between the 4), the stairs are triggered for ALL FOUR OF THE WARP RING POINTS. Why is it that they never go away, even when you quit or leave the area? The stairs should be reset.
1st/2nd quest-Odd feature
Actually, the stairs will only be activated if you arrive on a ring warp screen THROUGH the stairs. However, this is permanent because it was like that in the original quest. 😛 I'm not positive, but you might be able to use one of the beta 10 screen flags to allow these stairs to disappear. I think there was one labeled "Secrets are Temporary." Maybe try using that one. If it doesn't work, I'll see if I can come up with a real solution to permanent steps from ring warps.
