////////////////
bolderbrush10 github commit fixes it.

There is 1 error left:
1 Race / Surface will spawn only turrets in the far distance.

I just pushed bolderbrush10's fix.

"1 Race / Surface will spawn only turrets in the far distance."

I'll take a look in 1.17.3.

I'm not seeing the "spawn only turrets in the far distance" issue. I scanned a few planets with radius of 2000 - 4000.

May you provide your save?

I did some tests. Only one mod combination causes this error.

K2SE+ERM = ok.
K2SE+ERM+Armored Biters = ok.
K2SE+ERM+Explosive Biters = error.
K2SE+ERM+Frost Biters = ok.
K2SE+ERM+Toxic Biters = ok.

K2SE+ERM+(Armored, Explosive, Frost, Toxic) Biters = error.
K2SE+ERM+(Armored, Frost, Toxic) Biters = ok.

Explosive Biters with ERM breaks spawning hives (1 Race/Surface).
ERM Default doesn't have this error.

Also spawning hives don't work correctly.
Example, explosive biters will appear in ice surface: https://imgur.com/a/lyrEawW

Thanks for the tests. 1.17.3 fixes the fire biter.

Re: Custom biter on incorrect surface.
Yes. The enemy autoplace function in this mod does not compatible with those custom biter mods'. I have tried to balance them, but failed. It either have mass amount of default biters or mass amount of custom biters.

Thank you :)
