Is this working now? I'm reluctant to install it based on the comments.

Thanks man, fixed it

must just be early access jankiness

Strange. This mod just changes the loadout of the small airfield template (nothing else). It has a different file name so normally it should not mess up with other game files. Do you have any other mod enabled? Does anyone else among the subscribers has this kind of issue? Normally the other airbases should show up if 'All Countries' is selected in the Nation drop-down menu of the editor (make sure you're not in the USA menu, see the 6th Screenshot I've just added). When you uninstal a mod please make sure you follow these steps: 1) Uncheck the Small US Naval Air Station in the Mod Manager 2) Click on Accept 3) Unsubscribe. Also make sure the "3380763952" folder under "C:\Program Files (x86)\Steam\steamapps\workshop\content\1286220" is gone. Hope it helps.

Even after an uninstall, it doesn't work

What did your mod do

After I installed this, I can't place any airbases on the map in the editor anymore

Glad to hear you solved your problem. Yes, you can use Notepad to edit the .ini files = very handy ;)

It was the file extensions that was tripping me up. Windows 11 hides them by default so they where just .txt files instead of the proper .ini

Suggest you have a look at the mod, as an example. You should find it @ C:\Program Files (x86)\Steam\steamapps\workshop\content\1286220

Trying to have my own custom airbase like this with some of the modded plane variants but cant seem to get it to appear in the mission editor. Any tips as i can't seem to locate the issue?
