Opening Container GUI Rearranges Hotbar

Still consistently reproducible in 0.16.0, in both iOS and Android. Though the interface has changed (now using the inventory button to open the horse inventory instead of the more obvious look-down-press-Open button) the results are the same: scrambled user inventory. The interface change also has the consequence not allowing the player to change hotbar items while riding - a significant disadvantage over the previous method. In addition, the change has the effect of preventing a rider from leashing the animal before dismounting, as the Leash button now no longer appears when holding a leash and looking down - again, a significant disadvantage over the previous method.

In 0.16.0 the issue now extends to more than just the horse inventory. It seems that any change of a hotbar item causes the inventory to scramble when the inventory is next viewed through a chest, with the hotbar items becoming the first items in the inventory, and any items they displaced in the inventory order taking the place of the items that moved to the front of the list.

Unable to reproduce in 1.1.0.3 (was still occuring in 1.1.0.0 and 1.1.0.1)
Have tried chests, horse, furnace, enchanting table.
Looks like a fix,
@Allex Souza and @Jerry Doherty how is it looking for you on 1.1.0.3?

This bug is clearly reproducible on iOS (both iPhone and IPad latest version) MCPE version 1.0.7, 1.0.6, 1.0.5 and it is definitely not fixed.

Create a new survival map with a random seed with Pocket UI (This bug does not happen with Classic UI).
Play about 10min, create a chest and open exchange some items between your inventory and the chest.

Once the chest is closed, your hotbar will be totally mixed up.

1. The mcpe puts random items in the inventory on the hotbar.
2. Same item appears multiple times on the hotbar.

Priority is 0 since whenever user opens chest, hotbar gets messed up and user has to re-add / arrange items on the bar. After playing like a couple of days constantly rearranging hotbar, it gets very annoying and frustrating thinking.

On Windows 10, a similar issue occurs in a less severe way - it places the same item multiple times on the hotbar's open slot.

@Eric, yes not fixed in mainline yet but is now fixed in 1.1.x beta builds.
The fix should be with you soon on next IoS release I would think.

can confirm on 1.0.7 its not fixed - very frustrating - its first appeared with horse / mule inventories, now its all over! almost every chest you open rearranges your hotbar - mojang, are you even testing your builds?

jamino is correct that the bug is not fixed for 1.0.7.0, but I imagine that it will be fixed in the future. I have no experience in programming whatsoever, so I can't really accuse Mojang of anything. The problem affects me as well. Do your items in your inventory clone themselves, but do not actually increase in amount? This takes up valuable space in my hotbar.

I made an account just to report this issue.
Please fix, i have this problem on my Fire TV Stick (i know) and my Note3. Windows 10 does it sometimes too. Very frustrating to try and play like this.

This issues is still not fixed in latest version 1.0.8. At first I thought it was but after playing for a bit on 'Pocket UI' the problem has come back. I have updated all of my devices and the problem remains. The worst part is that some items may disappear (like a diamond enchanted sword that took quite a while to make) Easy to reproduce this issue, as stated above. Playing on windows 10 edition and Android (Samsung Note 3, AT&T) Please fix this issue. The "Classic UI" is not very controller friendly. Also it would be nice if item labels would show while navigating using Pocket UI but please fix the problems before adding anything new! I love the ui for xbox and it would be great if you could implement that UI on pocket edition.

The resolved comment indicates we'll see the fix in the 1.1.x update, so you shouldn't expect to see it in 1.0.8 (nor, probably, in any further 1.0.x updates). 1.1 betas are moving right along, though, so you probably won't have to wait too much longer.

Same here on 1.0.8. Hope 1.1 will fix that. Meanwhile I switched to classic ui. imo, it is even better.

Still have this problem, which is odd considering its status as "resolved".
