Could anyone's issue be related to creating objects at run time?
I have a project that works perfectly in 476.4 but not in 487.
Essentially, I have a JSON array that lists some images stored in local storage. I loop through the array and create a sprite for each entry and assign an incrementing instance var to the sprite. Once they're all created, I request the first image from local storage and load it into the first sprite, then increment the var and repeat until all are loaded.
But in 487, the first sprite didn't load on local storage get.
What I've found I need to do to fix is insert a wait 0 seconds after I've created the sprites otherwise the on local storage get doesn't trigger because it can't find the sprite.
I can't replicate in a simple minimal project I just created from scratch and I can't upload my project as it is as it uses a private back end so I'd have to deconstruct it which might take a while.
But the wait 0 workaround works for me, so I'm not too concerned - but just thought my findings might help others.
