The problem is that the writer (or designer) does something to break immersion. In order to fix the problem, they need to not do that.I think what we may be running into here is a difference of opinion about what “the problem” is. As I understand it, the problem under discussion is broken immersion. It seems like you’re arguing about a problem of inconsistent writing.
It's not my job, as the audience, to explain how their world is supposed to work. That's not even remotely what I signed up for. They built the world, and they should know how that world works. If the world they built is stupid, then they need to take ownership of that failure, instead of expecting the audience to bail them out.
One habit of terrible GMs is that they listen to their players speculating about some unknown, and then alter the reality of the unknown based on that speculation. They hear you speculate that the new Big Bad is actually the minion you abandoned six sessions prior, and decide that would make for a better story than whatever they had originally come up with, and retro-actively change reality so that it's the case. It's meta-gaming of the worst variety, and it's exactly the sort of thing you're suggesting.
