Nvm again, I've "read the *ucking manual" and regenerated seed.

Great mod! Thank you

Nvm, found the problem.

I downloaded ArumbaModPack and it seems his version of RSO was modified.

After I installed same version from original source everyting is fine.

Damn you, Arumba!

Another question, is there any way to add biters to existing save?

With 1.5.1 RSO mod and 0.12.29 Factorio bitters nests do not spawn at all.

I tried to turn off all other mods except RSO and results were the same.
Resources are ok, but there is no biters.

I tried max biters generation settings and it didnt help also.

Is there any solution?
