For the second time, I encountered an error message "Object reference not set to an instance of an object"on two of the splines on Hole 1. The first time it was the green and fairway. I fixed it by deleteing those two splines and recreating them.
The second time it was the grren and the semi rough splines. This time, I was doing some sculpting and had regeneratd the splines several times. Below are images of my unity screen and the error console.
Any help would be appreciated.
