Revised Gathering Rules?

It should be kept simple, but rules could allow for cotters to bounce off, bump, or cooperate, depending on the alliance stance and the size of the armies involved. We don't have the guard/aggressive 'stance' for armies, that other RPGs have.

I propose these rules for when a resource squares is occupied by your alliance:

1. 'At War' vans/cotter arrivals will follow existing rules (bump or battle).
2. 'NAP' vans/cotter arrivals are turned away,
3. Allied and confed vans/cotter arrivals will co-operate, to fill up a queue of vans/cotters.

Perhaps (3) needs some explanation. Say you send 3 cotters to a square, then another 10 cotters arrive from your alliance buddy. Those 10 cotters will help your 3 cotters, to speed up the gathering operation, filling up your 3 cotters, after which, your 3 cotters return home full. At this point, the 10 cotters will not have gathered anything for themselves yet, but they then start gathering for themselves.
