If you want to see a real schoolboy error in the procgen, look at the map of discovered neutron stars.On the one hand I admire what FDev has done with the Stellar Forge, but on the other I scratch my head in amazement at these procgen 101 rookie mistakes.
There are no neutron stars near the X, Y or Z axis in the whole galaxy, and it really sticks out like a sore thumb (e.g. look at the neutron map on Spansh). Basically one of the devs when trying to exclude procgen neutron stars from the bubble got their logic reversed - they wrote something like "if abs(x) < dist OR abs( y ) < dist OR abs(z) < dist then don't make neutron stars" (which results in no neutron stars near the axes) instead of "if abs(x) < dist AND abs ( y ) < dist AND abs(z) < dist then don't make neutron stars" (which would result in no neutron stars in a cube around the origin). It's the sort of error a developer makes once in their career, remembers it very painfully, and never makes it again because from then on they double check their conditional logic - suggesting that an undergrad might have been involved in the development of that part of stellar forge. It probably got overlooked because they just checked that there weren't any inconvenient procgen neutron stars in the bubble and called it good.
So schoolboy errors in the procgen aren't really surprising. The trouble is once they are in the live game they are disruptive to fix (requires a re-roll, and that's why the neutron stars near the axis problem has never been fixed).
