There is far too little Uranium.
This is an extremely irritating issue - whether it be a deliberate design choice or unintentional, Uranium is far. Too. Rare.
Never mind the nigh uselessly puny range of ore detectors compared to the size of asteroids making it difficult to locate any ore now (most asteroids don't even seem to have any ore at all), but I've searched over 200 asteroids only to find exactly one that had any Uranium.
Please change this.
