I'm trying to make a scenario using the Necroa template that plays like a standard plague at first and the zombies are only activated by an end game trait. The problem is, even if I set a high cure resistance my plague is cured ridiculously fast and countries close their borders, airports and seaports way too early. I thought it may have to do with the government actions tab, so I gave it the standard gov actions (not Necroa gov actions) through file editing. Now cure progress is slower but I still have the problem of countries closing off. If I can't find a solution, I will be forced to change the plague type.
