I feel like It's almost impossible to maintain a garrison when the town prosperity gets high (like 13k+ onwards) due to the high food consumption from prosperity. Will there be any changes to address this? I would think off the top of my head that it would make sense for garrison food consumption to be factored in first as a "base" consumption of the town so that any food shortages caused by prosperity wouldn't cause the garrison to die (since in theory the garrison would be supported by making sure the army has first dibs on food before enabling the rest to go to the general market). This would also then see that during sieges, the garrison could still "starve" since the base consumption was not met. Would something like this be possible? It would also really be cool if we could get a wider variety of policies that could attract more caravans to the town, or to have a bigger effect on town prosperity (both upwards and downwards).
Secondly, it would also be great if as a ruler of a fief or a kingdom, you could arrange "objective" caravans to purchase and import goods from other cities to your cities directly. Such as what Rome did when they imported grain from Egypt. It could even go so far as to have to be approved by the other ruler. This way, it could ensure that cities have sufficient food for growth, or even form a basis for a declaration if such imports were denied or suddenly stopped.
