[Grid + RVO Controller] Recalculate path

Hi everyone.

To be short, I set up a grid graph, and RVO Controller on some units.
My problem is that I made my units stop moving once they are at fire range of some target, that works well, but, when I have groups of units, the units behind are blocked by those in front, I’d like them to search a new path to get around non-moving units.

Any idea ?
