Hello, Mojang. About the glitch do not patch it. And also I think my armor wasn’t from toolbox. Last night(May 22 | 9pm) my armor’s durability is down(I think), but I joined again the next day(May 23 | 9am) the armor is still the same. But when I came back again at 10am (May 23) the durability is back to normal again??? HOW IS IT LIKE THAT, check the image here to see more.

 Normal - 10PM
