Well if someone managed to hit the mob cap without noticing, I would say it’s pretty likely a violation of S5#1. You would likely have to be afk farming (using an autoclicker and walking away) to not notice when bosses aren’t spawning in anymore. There really isn’t a reason to spawn bosses until you hit the cap since sentries and summons exist. Using just lunar portals and a stardust dragon you can continually kill bosses effortlessly without hitting the cap. If anyone else was online you could also claim S0#4 like you mentioned, since not being able to spawn in bosses in the dimension where this is intended to happen could easily ruin the experience of another player.
