I am playing as the Maori. I want to construct a campus on the plains hill with bananas which is located between two geothermal vents, two mountains, and another campus. That would be a 6x adjacency campus, correct? The tile had jungle a few turns ago and I removed it to make room for the campus. The tile graphically still displays the jungle, but the yield and tooltip indicate the jungle is gone, and the worker no longer has the option to clear jungle. I have bronze working (since I removed the jungle). The city owns the tile and it's not being worked. Is this a game glitch? The only other thing I can think of is that since the Maori can't harvest resources that might mean they can't place districts where a resource would be removed. Can anyone shed light on this? Can anyone figure out another reason why I can't build a campus in that tile? Thanks for all your help in advance.
