I tried modding in a race that doesn't have (or need) a Homeworld, by using the Pirate Faction as a starting point. So I added the tags to my custom race
Just like it is on the Pirate faction Defs.
The race does show up on the list, and the "Homeworld" field is empty. However, when I try to start the game, it'll say "Building Map" for a few seconds, and then instantly crash to desktop. No crash log or dump is generated (is that because we're out of Beta? Is there a way for me to force it to generate those?).
I understand that I might be pushing against the modding limitations, but where's the fun in conforming?
As a sidenote, and slightly related to my project: Is there a way to allow shipyards to stay orphaned, regardless of if we have enough planets to sponsor them all?
