Bug- using Shield Charge (Stalker ver.) in the BAF

[Indigo Blade]

I was playing the BAF on Excelsior last night on my Elec/Shield Stalker.  On back to back trials, I teleported using Lightning Rod on the first group of Warworks (directly after the opening cut scene) followed immediately by Shield Charge.  I clicked the destination of Shield Charge nearly direct below my character's feet.  This resulted in my character teleporting underneath the map.  Sorry I did not think to take a screen shot at the time.  I was able to return above ground by another person's Teleport Target.
