Inconsistently alpha of first object doesn't fade in transition

[nightfall708]

What did you do?

Simple transition between two view controllers, with one object with the same heroID.

What did you expect to happen?

Consistent smooth transitioning

What happened instead?

1 out of 4 transitions doesn't work well (supposedly randomly) as the first view's alpha stays 1.0 until the very last frame of the transition, instead of decreasing to 0.

Apparently https://github.com/HeroTransitions/Hero/issues/654 solves the issue. This is probably because my first object has a background layer.

I ended up adding modifier forceNonFade and setting the alpha to 0.99, but I am not sure why yet.
