Tried 12/13/14, xcode running latest version, multiple setting changes in C3.
Had a couple of xcode developers look at it but because it's Cordova, they have no idea. Another chaps looking at it now and said "the code is breaking it" so not sure what's going on, if some events or files are corrupting on export.
Just tried the canvas rendering method and still the same, crashing in the same spot each time (I've also removed this spot, an event based cutscene)and it's just crashing when the layout starts instead of letting the cutscene play/fade sprite fade in.
Weirdly, I made a button that goes to a random level and that worked.. made a button that goes to another cutscene level and that crashed
