So basically I am just giving the exact model and version of my device in the hope you can squash bugs which are probably annoying many people.
To remake the bug you can simply load a world (the app crashes).
Details of my iPad:
Available space left = 4.6GB
Version 9.3.5 (13G36)
Model MD528B/A
And so, that's about it. I ain't sure how helpful this is but thanks for listening
