Mesh index warning at extrusion

[Tim1234]

Thanks a lot, that fixed the mesh extrusion! It looks sweet now.
One last thing: I noticed that when the mesh is generated, the position is defaulted to (0, 0, 0) in world position. Therefore, there is an offset in where the mesh is placed (it's not placed exactly on the spline I drew - see screenshots for visualization). Is there a way to map the generated mesh exactly on the spline, instead of offsetting it manually?

Edit: I found out that I can copy the transform values of the spline into the generator, which fixed it, but I prefer to see an automatic solution if there is one.
