Awe. Yes, this does happen to me a lot. So I hopped into CubeCraft to try and recreate it again, as it happens almost every single game.
Attempt number one: A pair of chain mail boots appeared in my inventory; yet they disappeared without closing my inventory.
Attempt number two + three: My inventory gets closed, yet no chain mail boots appear in my inventory.
Attempt number four and five: Nothing happened. (obviously not gonna show a video of nothing happening, move on .-.)
Attempt number six: The exact same bug was recreated.
A clip, from 3 days ago. Since I record every single 1.8 game and
most of my 1.9 games, 'cause Sentinel, I found this.
My inventory was closed for no reason at first, then the pair of chain mail boots appeared in my inventory the second time, closing my inventory yet again, a second time:
As you can obviously see, it's more common than you might think. I have no idea how Chaos was not able to recreate it. Considering the fact she most likely tried multiple times to recreate it, not just one game of SkyWars.
This happens to everyone, it happens to me, so it must be a common case ... but I do not know, I can not say anything because I do not know if it's bug or not. But an iron boot appears to me.
I fail to see how you think that 1.8 SkyWars game play is supposed to come with chain mail boots in your inventory, forcing it to close, and then disappearing; then saying it might not be a bug.
Yes, it is a bug. Kinda annoying if you ask me.
I love how everyone that commented so far all have a different rank e-e
