Ok I had an automatic farm depositing items into a hopper that fed into a chest while items were being deposited I tried to remove some from said chest this lead to a bug where no matter how long I hold down on a stack on items I can only deposit or withdrawn one at a time no matter the chest inventory or so on id grade this the MOST ANNOYING Minecraft PE BUG EVER (update this has effected my entire game any save file now has the same bug)
