I fully suggest talking either in this thread or to the GM's (all of them) for any planned plots - in an RP you have to always expect that people will interrupt things as that's just the nature of how things move forward, but you also have to be very flexible as you're not writing a story on your own. Essentially the entire point of an RP such as this is that it's very reactive rather than pre-planned... I've intentionally kept the general situation at the moment very unplanned purely with the interest of seeing how people react to each other and the situation they find themselves in.
For example, I can say that I plan for Outworlders to become recognized by the general public (and labelled as Outworlders by said general public) sooner rather than later. I see it as an inevitability. I expect real plots will develop at this point in a way similar to that of a TV series rather than that of a film. By this I mean that antagonists will make themselves known and plotlines will naturally develop as a result of these antagonists... TV series can adapt to things like actors quitting, while films can not do that so easily.
Naturally, not all plans can coexist so not everyone's plans will work out. This is just how things are with RPs - they're a series of reactions rather than a novel written with a fixed structure that can be edited and tweaked until it becomes a full fledged thing. However, even when a plan is interrupted, that doesn't mean that the plan is thrown out - it could continue naturally in just a few posts, or it could adapt. Work with each other and create interesting developments that can leave everyone happy.
For example, you could plan on leading an army to attack a city, but then someone says that the army is heading to a different location. You can then post about splitting the army later on, and have the armies attack both cities, perhaps with different outcomes! Always remember that a diversion doesn't mean a dead end.
