Hi Jean,
Setup at the moment is to go into a plain scene with image in front of camera, load the playable scene after a wait of 5 seconds, and on hitting collider at the end loop back to the first scene etc.
None of the elements are persisted between scenes at this point.
Until the update, cycling through the above behaviours was fine, currently I can load into the first scene, successfully load the playable scene, and then transfer back to the first scene again. The crash happens trying to load the playable scene again, and happens also if I try just loading straight back into the playable scene (the log above is from this)
I'm using set property in two places in the playable scene, the drag value on a rigid body, and the target of a Unity Constraints component.
Saw your post about loading scenes in IOS with a JavaScript scene manager you trigger with a send message, and have been starting to set that up. Works ok, but I also have the issue with non-destroyed cameras, as well as render settings (skybox etc) being ignored. Haven't tried on the device yet, want to crack manually removing cameras an setting render settings first.
Thanks for the help, Nick
