I have found six bugs so far: (1) timeout that prevents Mecha upgrades with coin (2) timeout that prevents diamond reward in achievement section (3) after killing opposing player mechs in pvp, their wall becomes indestructible causing you to lose (4) if you exit pvp, the pvp damage chart remains on the screen (5) after completing the tutorial, a few minutes, the 5x speed for new players on launch disappears. (6) When switching between Quest, Mecha, Parts, etc Quest timers reset to full.
