Rainbow ore not showing in my inventory and obviously can't sell it.

I have found 3 rainbow ores in my second "achievement" run and they don't show in my inventory and when I go to sell they're not listed and hence, can't sell them. Found out they're worth more than diamonds. Is this a known issue? I hear a magical sound when I pick it up.

I don't see them in inventory either, only counted as an achievement. I have no idea if they're supposed to do anything other than count towards the achievement. By the time I even find any, I have no need for money as I make more than enough from the other ores to refill the battery and buy lights/TNT and I'm usually fully upgraded by that time.

no idea if it keep on count even after you restart a new save or must collect all 5 in one save?

They don't go in your inventory but the game does keep track of how many you have. I also believe there are more than 5 on the map so they should be pretty easy to find.
