I don't know what it is but I seem to only get 2 helium-3 when I mine 1 ore/ rock/ pointy thing. my ship is the Kamome with 2 heavy mining arrays and I have an IFF with the GMG with the GMG ID. I do not know what I'm doing wrong. I have used the wiki and it says I should have a mining bonus and it seems I am doing everything right as I have done the same with my gold miner and it is fine. it could be the ship. this "bug" bugged other people as they hadn't even got the faintest clue to such an extent where I had to make an account to get help! hopefully you have one.
