Possible to restrict faction traits based on other choices?
As the title says. I've had great luck using Ability Options with sovereign traits where you may only select one from amongst a group and wanted to do the same with Faction Traits. However, trying to use the same format only caused the traits to crash the game when selected. I also tried using Restricted Ability but that didn't seem to have any effect.
So, is there any way to limit options where certain choices prevent others from being selected? I have a situation where trait lines unlock building variety A or building variety B, and want to avoid instances of overlap if possible (as well as the fact that these traits might be too strong if stacked).
