First off there should be two things done to it. One would be a script to clear all landmines
Already done and in the Version 2 a lot of people don't have. I did post it in the original topic (I think it's in there, but if not, it will be in the rev 2)
set a time limit to the landmines so that they disappear after a certain amount of time (sort of like Rot's propane tanks)
Good idea, but I don't know if I'll do it.
