Found this on the ecosystem and looks good, however messing around testing some paths it seems like it has a game breaking bug in it. (Using Unity 2021.1.7f1 and PM 1.9.1)
So any time this action is used in any sort of state loop in playmaker, it breaks on returning to the start. Gives a loop exceeded warning and the movement doesn't work. Yet you can use it as many times as you want if you don't loop to the start...
I have other forms of moving the navmesh agent working in fsms fine, so it seems related to this action only.
