(Solved) Systematic error to spawn raid with hidden custom faction

[Hiztaar]

Hi everybody,

Here is my problem. I have made my Alien Xenomorphs mod. So I have my aliens race, pawns and faction. The faction is Hidden and obviously not humanlike. They are ennemies and should normaly spawn to attack. But here is the issue, everytime I try to spawn them, I get this error :

Of course they don't spawn alone and the manual spawn from dev console bring me that.

Do someone knows how to fix that ?

Thanks

I'm not exactly sure but it looks like the storyteller is having issues creating the raid alert. Do you have labels and plural labels for your faction and pawnKindDefs?
Compare them to the original defs and check if you have a value for all the different tags they use.

[Hiztaar]

I don't see any difference in the mandatory tags. I removed those useless for a permanent enemy faction.

I can show you the files if you want, you will see.

[Albion]

Just as an fyi for everybody else who may or may not be reading this:
Hiztaar did send me his files and looking through them I finally realized that his custom race was missing a <intelligence> tag.
Adding this resolved the error and the raids now happen as intended.

Thanks a lot Albion :]

Sorry to dig up an old thread, but you guys just saved my life. I've been debugging this issue for hours, trying to figure it out, and having no luck whatsoever.

I have a new faction, and new race. When raids spawn, I'd get the below errors. There's no indication of what the heck the issue is in that error. Thanks a million, and I will post the full error stack here once again in case anyone else is searching and searching. Thanks a million Albion for adding that followup post!

Mouse position stack is not empty. There were more calls to BeginScrollView than EndScrollView. Fixing.

And this is why one should always post the solution of a problem.
Future modders with the same issue will always appreciate it 
Glad we were able to help you.
