FIX THE WHOLE IOS VERSION PLEASE

I tried the new stairs and i saw if u put them at some angles they suddenly change textures! I made a building and when done reloaded world and everything was gone that i built! Multiplayer crashes when you use a chest as second player(joined one) and if a sign breaks while writing u will crash too! Place sand in air and 8/10 times it dissapears! If u equip for example a iron helmet while already wearing one the one u already was wearing will dissapear! And a lot more bugs in the ios version!

THIS UPDATE RUINED MY LIFE OF PLAYING MCPE! Cant build anything without it dissapearing >;( FIX PLEASE
