yes, meaning there should be a plan: what to visit and when, what resources to gather, what peasants to bring in, and what else to collect and transfer – otherwise, you might lose units without any movement cost.

It's not necessary to load through the exit; the main thing is that the first day should start with a "clean slate," and then any subsequent loads will be without glitches (especially if it's a regular repeated reload and replay)....

I didn't quite understand about the loads and the "clean slate." What would be a "not clean slate," and what should I do to cause glitches? In any case, loading each save through Alt+F4 can't make things worse. So, what should I do about Ghashra, esteemed bolotnik? Do you suggest waiting a month, gathering an army, and hoping she attacks the castle, or should I give up on her, sacrifice 30 archangels, quickly kill Jorge, and move on? I can send you a save file if you're interested.
