Hello and Thank you for updating bob's mods!

In the version of factorio 1.1 I played with bob's enemies and since I love death world, around my base was filled with small artifacts, I mean tons of them. Do they add lag to the game? In the 2.0 too?

I am playing now a 2.0 version with almost all bob's mods and I am afraid to adding this too because of the artifacts.

Is there a way to add the enemies but not the artifacts?

Yes, there are mod settings to disable the artifacts.

You can just disable small artifacts, and that should stop enemy units from dropping any artifacts at all. In that case, only enemy structures will drop them. However, there is a new artifact radar building that we added which will gradually automatically mark any artifacts in range for pickup by your construction bots.
