SketchUp's built-in tolerance is 1/1000"
If your initial circle's segment length results in FollowMe geometry edges of shorter than 1/1000", then they won't get made - because SketchUp assumes the two ends are coincident and so skips on.
Then any dependent facets also get omitted etc...
This occurs in any operation making new geometry - like the native FollowMe, Intersect etc and any similar Plugins...
As was said before... Scale up temporarily to avoid these issues.
