Tween Not Working On Android

[Gaudon]

This is from the ADB debug console:

1. 03-19 09:47:53.706: I/Unity(15424): NullReferenceException: Object reference not set to an instance of an object
2. 03-19 09:47:53.706: I/Unity(15424):   at UITweener.Update () [0x00000] in <filename unknown>:0
3.  

How do I even begin to debug this? The issue isn't present on PC.

Edit: There certainly doesn't seem to be a way around this. Other tweens seem to work, I can't begin to understand why this wouldn't. It's not the only tween I have assigned to a UILabel either. I'm just going to have to remove it and perhaps find another solution.

I've surrounded everything with null checks, and nothing comes back as null (expected since I don't see this behaviour on PC).

Yet when I run on android the labels with tweens disappear.

Turn off multi-threaded rendering. It's bugged to hell and back. That's about all I can think of that would cause weird issues.
