The inability for the player to access their inventory or party window during a siege has been a frequently voiced "beef" throughout the forum. Not having seen anyone look into this, I thought I'd do so and post what I worked out.
For whatever they are worth, the following minor bits of code/tweaks allow the player to have some added flexibility when besieging a town or castle: they player can exit from the auto-rest and access whichever menus they choose, without canceling the siege. Further, they can move within a certain radius of the besieged center with the siege continuing and if they move beyond this radius, the siege is terminated. At half the limited distance, a message scrolls on screen, notifying the player that their siege lines are stretched too thin and serving as a warning.
Since some Native code needs to be tweaked, I've marked the edited Native code with three comment hashes ###
This Native trigger needs to be tweaked: one else_try block needs to be commented out
