Did you "refreshed" the plugin after update? Just open it and go to every parameter to "refresh it", even if you no change anything. Did you configured the obstacles and where they should spawn?
Viewing post in Obstacle Won't Spawn
I completely removed the plugins from my game then copied them back in (which I had done before, but I think I did a more thorough job this time). I had to fill in the parameters since those seemed to not get copied. This seems to have fixed the obstacle spawning, but now my time HUD isn't working XD Trying to figure out what the problem is with that now.
