Easy solution is not let people retry failed leves, I believe it was like this back at the start... and I believe people abusing the system is why the devs where hesitant on adding it.

Aka you fail levinshower you only have a 33% chance or what ever it is to get it again next reset. Would stop the fail leves instantly.

Loved doing some grid leves with my ls for a change the other day and having a few members saying "oh I can't get leves because I will lose Levinshower, ranin reveries, all cracked up, and dunes folk." This is something that should of been patched months ago.
