this mod is all about buying stuff that you cannot yet afford to produce or to save a lot of time. its usefull to buy the first 1k plastic, some nuclear fuel for your vehicule.
the alien ore is supposed to only drop from enemie, that in itself is not that rare but someone playing peacefull cannot obtain it easily. Can you make some kind of check to see if the world is still peacefull ( i suppose its not once hostilities has begun ) . the ore value is far higher if the player has to aggro the whole map to get some than if some biter will come every now and then
Anyway, i did not play with it enough to give "balance" advice yet, i just started a new game after a few month of non-playing
