Mod is great, working just like 1.1 rampant, had a blast of a game, with a gamebreaking problem (for me). Can't disable the undergound attacks!
Getting flashbanged while working on something due to the biters tunneling for my nuclear reactor was fun for two or three times, but the incessant underground attacks are just not that fun. And the config to disable it doesnt work. Can't spend 5 minutes without suffering a coordinated goblin attack on 3 places, to the point i'm near calling my campaign dead. Besides this annoying bug (no pun intended), mod is great.

I checked - disabling underground attacks works correctly. Maybe you didn't find it? They are disabled in the mod settings, in the "map" section.

By the way, it is quite easy to defend against them - they cannot pass through turrets or radars

I did find it, and tried both options, by turning off the underground attacks checkbox and putting the attacks on 0.01 (the minimum chance possible). Maybe in a new game it works, but in the current save (20+ hours) it didn't. I opened to check and it was disabled and still ocurring. But it would make sense if it doesn't work on ongoing saves, as it's based on map basis. I'll try another save, thank you for answering, and thank you for reviving the mod, it's really good.
