I've posted my mod here but when you run it in dev mod you get an error, it doesn't affect the game or generator it seems but it's just annoying.
I know it has to do with the fact that it does not like that I messed with the world generator and removed factions that way, maybe there is a better way? I'm posting this in unfinished although its already on steam, it works but just the small error.
Anyone got a fix for me? It's probably something small I am missing!
Thanks for the help in advance! Error only shows up in DEV mode won't show up with out DEV mode on, which is why I published the mod as is.

You are in Luck, there is :

Yes i know about Rainbeau's faction control, but I'm making something different

But you could look up how he handles removing factions and events

It would be helpful if you described what you Plan to do.

Yeah Rainbeau's mod isn't done with def's I think it's done in c#? I can't look at any of the things he does.

The mod I am spawns no factions or animals at so I'm getting a small error when the mod starts up. I just want to make it so I won't get that error.

If you want to try the mod out or take at look at my defs go ahead it's on steam!
