Crystal core isn't moving a silverwood node

Crystal core is set up properly. I touched it with a wand and it went pling.
The little node from a silverwood tree I planted is most definitely within 24 blocks. I went 20 to be on the safe side and in a straight line.
So I touch it with wand and the crystal core goes pling and rises into the air and settles down and stops. No beam, no effect on the node.
Is the node too small for the crystal core to see or something?

I think the max range is actually 20. Its sounds exactly like its out of range. You might just be outside the range by a fraction of a block.

It's 20 blocks counting the core and the node.

24 is what I have seen in all the videos.
But anyway I ended up enlarging the node quite a bit before I attempted to move it again. Since then I have moved nodes up to 23m away from the core successfully.
Some of the little silverwood nodes are just hard to see I guess.
