Do claims ever expire in Survival? If so, after how long does the player have to be inactive for? I'm asking this question after a lava cast was made all over a town I am in. You could say that this is following up the issue of griefing near claimed land deliberately, which I also think should...

So I gave someone 1 billion and 9 stacks of IG spawners for /fix on survival... Now I'm curious if I just gave the best value deal in IL history? Thoughts, please...
