Every single time I join any of my worlds, let it be from the lowest bits used to the most even brand new ones it crashes 1-2 seconds after i join. This is an extremely important Game breaking bug that needs to be fixed otherwise the game is unplayable. Ive tried restarting the app and my iPad but nothing changes.

How to re-create?
I dont know. Ive tried everything to fix it but I have no clue what caused it. It just started to happen right when i played it the first time today, at roughly 3:20 pm. The last thing i was doing on it (the day before) was playing on my survival world (when i reported my last two bugs) i quit after i died and lost all my stuff in the relocation bug i reported. The world i tried to go on when it first happend was yet again my survival world, i then tried my creative world and then one of my older worlds and not one was stable, every single world would crash my game.

Edit: To Answer Mega_Spud's Questions
-Yes I'm always using wifi when playing or no connection at all.
-Yes it dose happen on Airplane Mode but it takes a few more seconds for me to crash. Around 2-4 rather than 1-2
-Yes I am logged on using Xbox Live. (Ive heard rumours from my friends that got Xbox Live that it breaks their game too so this could be it, I have not yet tried it not using Xbox Live)
-No I don't have or use any Texture Packs.
-I'm on iOS 9.3.3 currently. I entered that in the box when I submitted it but it doesn't show up for some reason.
