Hi There,

I made a spline in an old map as a ribbon to direct the player around a maze, but going back and making changes to the maze and now needing to make changes to the spline I have found that it can no longer be extended?

This is the BP I’m using:

Any ideas on what I’m doing wrong?

Would massively appreciate some help!
