When generating maps with small or very small starting areas it is only spawning the ores half of the time and if they spawn then only in the starting area.
if i set a big or very big starting area i get insane amount of uranium ore but only in the starting area.

can you make it so the ore is always outside the starting area and spawns like the other ores? That way i can count on it being on the map even if it is further away.

Are you using Resource Spawner Overhaul (RSOMod)? It's a very popular choice and might help.

Of course it is spawning further out. You surely missed them.
