Machinist: Ricochet ability is apparently "Not a valid action"

The use of the ability Ricochet as a line command results in the "Ricochet is not a valid action" message as well as no activation of the ability.

While attempting to use the ability within the text prompt or within the User Macro editor the following commands are apparently invalid or improperly coded to the Ricochet ability:

/micon Ricochet (result is no icon being shown)

/ac Ricochet (result is error message and no action being activated)
