@pineappledan Instead of NONE word leave blank tile. Will be better to read.
IMPORTANT ISSUE!
Ok, I found the issue with Arsenale di Venezia but.., yeah there is always but. So:
1. Arsenale di Venezia, Muralto Glassworks and Rialto District ARE NOT set as Venezian uniques. If they where they would show up in player choose menu like all Pogost's Stages,
2. They also have unique buuildingclasses with DEFAULT building set. So that's why they show up for EVERYONE.
3. I set up Pogost 2 and 3 differently. I DELETED them from default building too not show up for everyone and set up as unique so they show up in menu.
4. When I choose Pogost 1 to be in guild tech then it is set as last building in tech list and arsenale di venezia shows up (because it is visible by anyone).
5. If I set rialto, murano and arsenale's buildingclass defualt buildnig to null then they dissapear, but also cannot be used.
6. Then I need to set them as uniques and they appear in the menu.
7.SO, what option to choose? I can change Pogost tobe like Arsenale (visible by anyone, needed change in description to tell about 3 stages (2 are not visible in menu)) or change Arsenale to be like Pogost (it will be visible in menu).
8. And last but important thing. When Default building in buildingclasses are set to null then They NOT show up as excluding building, or prereq buildings. The are needed, but player is not informed about in main menu.
