So I tried the Onyx Hive for the first time in my new playthrough. Is it just me or is their a problem with their growth rate? There growth rate is meant to be linked to your Promethion supplies. However when you mouse over the growth rate on a colony there is no modifier for Promethion. In my game I had a fairly high amount of Promethion supplies yet I was looking at 15 to 20 turns for 1 pop growth. This doesn't seem right to me.
