You're a damn hero.

Yup, I 100% agree!!!!

It worked great, I play on a server with a friend and we had problems with biters sneaking into our base as we had no defence.
Now we just disabled expansion and have some peace finally.
It is also no problem if you want to get achievements, just change some settings and then load the save again without the mod for steam achievements.

Thanks, this is why I updated it. Some people start an Island map, sometimes in multiplayer, and their whole playthrough with their friends gets ruined if they can't fix ther map without disabling achievements. And now in Space Age I've seen people accidentally have horrible Asteroid or Spoilage settings, and not realize until far into a playthrough. Most games let us change settings mid-game without "cheating", but at least in Factorio mods are a workaround.

‘d agree!
