I play on iPod 4, latest software update, and most up to date DS version

I am level 118, fully expanded, full quota of habitats, with 114 dragons. I have the battle arena and, since yesterday, the quest outpost. I have all the dragon boost buildings, 1 healing pool, 1 stable, 1 trading portal and 1 spell shop.

My island is fairly extensively decorated.

My problem is that once I have collected from all my habitats, completed a battle and harvested and replanted my crops, by the time I reach my breeding den 8 out of 10 times my game crashes. It is nothing to do with visiting neighbours because I rarely do!! My guess is that my islands are too full of animations and the game cannot cope. (I have a second account on my android phone and am unable to visit my IOS islands as it causes my android game to freeze).

My question is - will removing all unnecessary decorations improve the game play? I would rather not, obviously, but if it means my game stops force-closing itself I will do it.
