Anyone know how to generate new faction leaders?

Runtime GC has an option to regenerate faction leaders

Could try spawn world pawn from dev menu

One of my race mods seems to be bugged (error doesn't specify a mod unfortunately), and errors occur occasionally with pawn generation. I presumably didn't notice with these two, and now they're saved that way. Is there a way to try and generate new faction leaders? I found a few posts like this, but they all refer to runtimeGC which I'm sceptical of given that the unofficial 1.3 port "has only had the bare minimum to get it working again" done.

Also, has anyone found similar bugs when using revia race mod? I get random issues when enemies/animals try and attack my colonists occasionally too, and the errors aren't helpful (all either point to methods that aren't present in vanilla rimworld, so I assume come from Harmony or the parent race mod, or are null reference exceptions so I can only follow as far as the unexpected null value).

If the other fellows suggestion doesnt work (e.g. pawn wont load to spawn) try dev mode "kill faction leader" might have to go through a fair few of the factions first though
