Hotbar Items constantly change

Hi there,

Please can you fix the following bug -

After crafting, opening chests or using a furnace the items that were placed in the hotbar suddenly change to other random items that are being held in the inventory.

i.e. Each time after I craft or open a chest or use a furnace i have to then remove all the items that have been randomly switched out in my hotbar and replace them with all the items I had in my hotbar before crafting, opening chests or using a furnace.

This happens on iOS system on my iPad and my iPhone.

Many thanks in advance.

Kind regards,

Stew.
