It's just the inspector throwing exceptions though. That's weird.
Will take a look at it.

Well, your line numbers don't make sense. It's probably before this got moved into the namespace.
But I do assume the null reference is this line: https://github.com/EsotericSoftware/spine-runtimes/blob/master/spine-unity/Assets/spine-unity/Editor/BoneFollowerInspector.cs#L51
In which case, it should be a null check before that.
I'll push a fix in a bit, but you should be able to take care of that specifically on your end for now.
As for it not working until you selected it, if you create a BoneFollower at runtime, make sure you set the fields yourself.
What it was doing was filling in the fields when you selected it.
