Hey there, thank you thats made it work perfectly 
I was worried the system wouldnt allow me to do what I wanted and I would have to stay grounded or let my units run up walls 
As I should be removing array items before the teleport, im assuming I should be readding after the teleport instead of the current set array elem, which in this case would now set nothing.
As usual I appreciate the work you do and would love to hear feedback from you sometime on my current build, though I understand your very busy
