Setting to disable sappers?

[babaGAReeb]

I want to play in a simpler way and only want raiders to come through my killbox

so how do I disable sappers? I have only tribals as enemy factions

How to search the internet for my needs?
At the current state most websearch engines are pretty clever, you should compress your question in one sentense (how do I disable sappers?) and maybe add to the search text for what it is needed (Rimworld).
It is important that you use the right words, special if there are some theme related terms (sappers).
Mosttimes you get plenty results.
Ofcouse you can search at the related website and use the search function there too.
Like for Rimworld the biggest mod database, the steam workshop.
A simple search for sappers allready give you the result you ask for.

And when you say, you don't have a steam account to get the mod, use one of my signature links.
