If the barracks is present in your town it will be considered by Alcatraz as an option to draw from (regardless of road connection). Syphon's question was actually answered by that post (I'll state the answer again just in case) So as general advice, if you change your military building set up or age up it's good to refresh then collect from your GB's. If you have them ready to collect, then research the first PME tech, then refresh your browser and then collect it should give you the new PME goods.Įssentially what you collect is 'predetermined' from the point you log on, logging off and then back on resets the collection point to your latest log on time (and your ready collections that are age/random dependent will update to what you have at that new point in time). If your Atomium/Observatory is ready to collect in say ME and you then research the first PME tech, if you then collect right away you'll end up with ME goods. I haven't done this personally but I know of players who have done this and it works similar for the Atomium/Observatory. However if you change your set up (use a reno kit and drop/add a bunch of buildings) and then refresh your browser (to be safe you can completely close and re open the browser) it should refresh what troops the alcatraz is going to give and you should end up with random troops from your new set of military buildings.

From what I know if you leave your Alcatraz ready to collect, change your buildings (via building/selling or using a reno kit) and then collect it will not update and give you units from your old set of buildings. The answers to A and B are pretty much going to be the same (assuming B is referring to using a reno kit on a champion's retreat).
