Hello staff members of CubeCraft. There is currently a bug in Eggwars that involves upgrading generators for free. It is not simple to perform this cheat. But when done correctly, you lose no resources. Let's say that I have a broken diamond generator, and I want to upgrade it. I currently have 7 diamonds in my inventory and it costs 5 to upgrade. I must have the EXACT number of diamonds in order for this to work. So, you throw out 2 diamonds so you only have 5 in your inventory. ONLY 5. When you have 5, simply put it in your off-hand, and upgrade the generator. You will upgrade it, and you will still have your 5 diamonds in your off-hand. Then just go pick up those 2 diamonds you threw on the ground. Hopefully this is understandable. Thank you for your time!
