Could you tell on which spots is this happening?

I can't specify it exactly. Sometimes when I build an aerodrome I can't build any aicraft. When I hover over air unit in the city menu, I get message "can't build because spawn point is invalid" tooltip. Building the second aerodrome usually helps. But not always. I tried to test it, but didn't find any regularity with this bug.

I'll take a picture of the locations but one city I had to have the areodromes connected to a airport or connected to another aerodrome while connected to a district. Another city I had to put the arrodrome on a low area and the high area didn't work. It honestly seems to be quite a few areas. Maybe my save is glitched lol I have the save on a 601 turn if you want me to send you it and tell you which cities I am having the problems with.

I mean, yeah it looks like a bug, so if you found the save file, it would be nice if you could create a bug report

Will do, probably gonna be sometime tomorrow when I make that report. Thank for the reply.

I can confirm this bug. Hard to say what triggers it, because it seems random. So the areodrome is built but you can't construct planes because it says: spawn point invalid. 

It is triggered by buying out the aerdrome in my games. If I let it pop out with industry then it works just fine.

I've got the same bug, very annoying. It's been several months and six batches since this was brought up and a developer on Reddit already informed they're aware of it. Effectively the bug may prevent having air force in the game at all, depending on the number of cities and territories you have, so I wouldn't consider it minor.

The samething happened too my nuke silos. You just have to make multiple of them and eventually they will pop on. Or connect them with another structure is what I did to get them to work if the glitch happens. Some won't every be valid though.
