In my save you can take a view of the exact moment of spawning and consequent destroying of my perimeter defense. It’s funny ))

Now I run special killer-train, that takes artillery shells at the factory and roams around my wall wiping out biter bases.

At present this is the only solution

What are your map settings ? Are you playing modded or vanilla ? Maybe you can add a save ?

I play vanilla game.
Here is autosave (can't upload 25 MB file right here) - https://www.dropbox.com/s/5q9tei3vf8weu32/_autosave1.zip?dl=0 .
One behemoth worm will suddenly spawn after about 1 minute ...

Worms can spawn too close to my perimeter defense (less than behemoths shoot range, but far than turrets range). Behemoth worms suddenly spawn, wipe out perimeter defense and I don't have time to get to that hot spot. Is this "as designed" or a bug?

Definitely! But too late for me I have energy weapon damage lev.12 already

In the end, I did the same. I've doubled amount of laser turrets, and stacked large amount of science packs (except green and red)

Hi!

Does anyone know exact military tech conversion algorithm between 0.16 and 0.17?

In my case "Laser weapon damage" of 14th level converts to "Energy weapon damage" of level 7, so laser turret damage bonus drops from +720% to +300%, making my perimeter defense system almost useless. Is is a bug ...

Old icon was MUCH more beautiful. So, I'll stay on 0.16.50
