I built some airfields, but it says they are invalid spawn points. 

At first I thought it was because they weren't connected, so I built some more districts to connect them, but they are still inavailable.

I have not had this problem before.

Thank you! (Right of the oil field)

I haven't confirmed this bug myself, but @neprostoman mentioned in this post that this bug is due to buying out the aerodrome:

Oh mine didn't happen from buyout. Guess it's a different bug. The only way to get it working was to build a second airfield, after which I could select either and build planes.

Hola! Yep it is a known issue, we are working on it. Could you share a save + diagnostic file?
As a temporary solution, you can try to build another Aerodrome.

Yup, happens to me at least once every game, usually multiple times.

I ALWAYS play:

1) 5 to 8 AI opponents.
2) Huge Map with 70% water and 4 or 5 continents and New World

3) Endless

4) Difficulty is either Metropolis, Nation or Empire.

Doesn't matter if I use buyout or not.

Doesn't matter if it is connected or not.

It is always confined to one City and attached Territories at a time.

Building a second has NEVER fixed the first one for me.

Often times the second and third are bugged like the first one.

Replacing the bugged one with a different District before building a second Aerodrome doesn't work either.

The only cure for me has been to wait some number of turns and try again. Eventually it works again, but appears to be random as to when it will eventually work.

Like I said though, for me, it only affects one city and the attached territories at a time. I can still build Aerodromes in other citys' area of influence while it is bugged in the other one.

I have noticed this as well in my last play, which was for once in Endless mod. Maybe this bug has something to do with it...

Hey, still i will ask you for a save + diagnostic files
If you build another Aerodrome, is working? I know is not ideal, but trying to see if that works

Hi, here are four savefiles and four diagnostic files, which may allow you to replicate a couple of defects:

1. Aerodrome districts are "invalid spawn points", even after building a couple in one city.

2. Game crashes after a few minutes. (My tentative diagnosis is that there's a memory leak in the dynamic storage allocated within the GPU. I'm running Win11 on a Lenovo Yoga 7 Slim 7i Carbon; its Intel Iris Xe Graphics is running Vulkan 1.2.176.1. The game fails to load with the -force-vulkan flag; and I'm not willing to risk bricking my laptop by mucking around with Vulkan 1.3 until such time -- if ever -- that Intel has supported it on their Xe Graphics.)
