Hello @VoidVector
Thank you for the information and files, we will investigate further.
To answer your question on the other thread. It seems there was a miscommunication.
We put in a fix for regarding homegrown status in our latest update, but it was a different issue that arose as part of the testing, NOT a direct change to fix the issue you originally raised, which is the fact that you added random rules that don't exist in real life in the editor and they are not working because the players do not have a homegrown status stored if the nation does not use such rules in real life.
So your case is an editor issue rather than a Rulegroups issue.
We apologise for the confusion.
