Maybe a bug

So, whenever I'm on the game sometimes I put my phone down or I go to a different tab to reply to a message. Let's say I'm crafting, right nwo iron bars, my iron ore income is far higher than one smelter uses 1k ore, so my ore while I'm on the game goes up, but as soon as I'm down doijg what I am say replying to a text, or even this post, my iron ore is magically in the negative and is close to zero. Is there a penalty to your production when your not in the screen? If not then something is going wrong here, its happened with all resource types that I've tested it with. Can negatively affect the income I. E make my galaxy value less since I've lost resources. Its as if the resources disappear. I don't have more items made, just lose the resource.

Other than that, brilliant little idle game! Reminds me of idle evolution 1/2 by incremental Inc. Great dev and lots fo updates thanks for the Wickes game mate
