Hello! I have a question, I am quite new in the game actually. I just upgraded my Mammoth to M1. I did that after I upgraded the Protection and Weight parameters fully. So I saved some money (which I used on updrading the 2 parameters). I thaught that when I reach M3 I can theoretically upgrade ALL parameters fully, to maximum. However, I realised that I can never catch up on the 3 other parameters which I didn't upgrade in M0 state. Even though I upgrade them in M1, the previous "slots" are lost. Is that true? If so, I am very sad :-( Here you can see what I mean. The 3 stats in M0 are white and unupgraded. Are those "lost point slots"?: Thanks for reading, and thanks in advance! Kristofle
