I'm trying to do an upgrade on my Thunder from Level 8 to Level 9. The new chart after the 4.8 version said that the upgrade time changed from 24 hours to 20 hours. The chart at https://warrobots.fandom.com/wiki/Thunder agrees with that, and says the cost should be $3m, but in game (Android version), my upgrade on the Thunder shows at $6m and 2d 2h. Can you please check this and see if it is an anomaly (and is incorrect) or if your upgrade advice is incorrect?

About the position of the button to activate healing, etc. ... nobody is talking about it anymore, but you promised that the button would be moved for this version. Where it is... I can't concentrate all the time to miss the button. My thumb will naturally hit it. The button should be moved. Further, I don't even concentrate on using the button. I have given up. The button will activate healing, even when I haven't received a single shot. Please, please... move the button. If you don't, that part of the game is useless to me, and gives others who handle the button a tactical advantage.
