There seems to be an issue with ore generation. Right from the start, I got tons of uranium and this effects gameplay. With default settings on everything. Factorio version 16.51
Not a bug. Using the Perlin mode, Uranium is relatively rare and easy to path build around. You can try a few different starts and you might appreciate having that much uranium accessible compared to other spawns.
