Good morning,
I've performed a search on our forums as well as google for both UnitCastingInfo and interrupt. I see no documentation
here:
http://wowprogramming.com/docs/api/UnitCastingInfo,
here:
http://wowwiki.wikia.com/wiki/API_UnitCastingInfo, or
here:
http://wow.gamepedia.com/API_UnitCastingInfo
that the API has changed. As such, any cast, be it an interruptible one or non-interruptible cast such as mounting or hearthing, is always returning false (aka interruptible).
Am I missing something? I haven't seen anyone post about this so I feel like I'm taking crazy pills.
