Calling a protected function (IsItemInRange)

[stako]

Describe the problem

BigWigs occasionally attempts to call the IsItemInRange function on a friendly unit during a boss encounter - this is forbidden & will trigger an error.

What steps will reproduce the problem?

1. Engage Nefarian in Blackwing Descent on Heroic difficulty
2. Get mind controlled by Nefarian's Dominion ability so that Nefarian becomes a friendly unit
3. Wait for a mechanic (e.g. Tail Lash) to attempt to call the IsItemInRange function via the boss:UnitWithinRange method

What version of BigWigs are you using? (Stating 'latest' is not useful)

357.2 (357-7aae289)

Do you have an error log of what happened?
