Title: Made the mech recharger computer display a warning when the mech cell is faulty

Players were often wondering why mechs weren't charging anymore after upgrading cell : chances are it was because the cell had critically failed (can't recharge anymore), as the reliability was < 100.

So, made a warning appears on the mech recharger computer to inform the player the mech power source is faulty and needs replacing (reducing confusion).
