DISCLAIMER: I have played Factorio 400 hours and have only built couple bases which have launched rockets(plural).
So, i played a little with the new oil in a fairly new game.

As the update dropped, i had automated red, green and military for 45 spm for my new base, had established a pump jack ...

I think the change is fine. The amount of long posts here is insane, since there really isn't any discussion going on, only people forcing their ideas unto the developer.

I would be fine with any change to oil, I mean, if you really want to complain about oil being "dumbed down", why aren't you ...

How it happened: I was mining the scrap pile at the very start of the Arrival mission, after finishing mining it I got the error message. Im guessing the tutorial shouldn't end here. Also i dont think the tutorial bot was giving me any instructions except for the very first WASD.
