I would not delete a GB just for an event, but I have deleted plenty just to make space. Have only 15 left now. I see a lot of players that have blacksmiths for production quests. I don't. I have 12 fanshops. They will take care of the production quests. Reason I don't use blacksmiths is that sometimes the quest asks you to do productions from your age. Fanshops cover both. Next to fanshops, lvl 1 cidermills are a good alternative. I have an Alcatraz, but no rogue hideouts. I hardly ever use rogues and there are plenty of other ways to get them. Because of the Alcatraz I have 1 militairy building. It is 7x4. Whenever I need space for an event I delete the militairy building. Since I am in SAJM I no longer have the Unbirthday Party RQ, so when I need to collect coins or supplies I also delete the militairy building, place it back and delete it again till I have completed the quest. That's how I do it on my main world without ever having to use a store building. All my other worlds are diamond farms. There I use the same tactic for production quests with the exception that I have 1 hunter's cabin, to make space when needed. Nowhere do I need to use a store building.
