Target.Distance returns "-1.#J" ?

[Marze]

My macro ran into a bug and stopped:

Code: Select all

Failed to parse /if condition '(-1.#J > 25)', non-numeric encountered
macro.mac@72 (FollowMob(int MyTarget)): /if (${Target.Distance} > 25) {

What on earth would cause Target.Distance to return -1.#J ?
