[Solved] Campaign Editor does not find custom data for Techtree Requirements

[ebontope]

I'm currently trying to make a custom campaign, but early on I've already ran into a fairly significant issue. I did find a thread with a problem similar to mine here, but the images in the thread are no longer visible and I don't completely understand what fixed it for this user.

I'm trying to add a Techtree Requirement for one of the custom buildings I've made. Specifically, I want the Compound building to be required for the player to build a Gold Stash. However, the Campaign Editor does not appear to pick up the custom Compound building at all, as seen here:

I currently do not have any maps attached to this campaign yet, as I first wanted to properly flesh out the playable faction.
Is there a way to fix this problem, and how can I do it?

I'm able to reproduce the issue and it fixes itself when you attach a map and right click > Edit Map to have your campaign "loaded" in the editor

So make a blank dummy map and work from there, you can delete it later it makes no difference

This solved the problem! Thank you very much.
