Does anyone know the latest on the frozen tunic / rune arm bugs?

I recall reading a while back that there was a bug which meant wearing a frozen tunic caused your rune-arm to not add extra damage to your bolts.

Is that still true? Is there a sequence of equiping the tunic / rune-arm that limits the problem?

I am thinking about grinding out a tier 3 tunic, but don't want to fool with it if it is still bugged...

Thanks!
