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).
