You are correct regarding the limits of probability, but but it is also the Dokkaebis' job to alter the scenario in small ways to keep things interesting for the constellations/viewers so small interventions like removing a few green zones are perfectly in line with this specific scenario. Plus, in the situation that Bihyung messed with this time, many of the constellations already wanted more death and a far more "stimulating" scenario, so the probability's restrictions would be far less strict and penalizing for Bihyung in this situation. Thanks for helping to clarify my post though, probability does become a huge pain in the ass for many characters (especially the MCs' party members) to deal with later on in the story. Also, both our comments are slight spoilers for webcomic-only readers so I put this in a spoiler tag, I won't report your post as a spoiler though, because I know it's quite annoying to have someone else edit your post and your spoiler wasn't even a big one, you just mentioned the probability system before the comic does.
