Spacetree broken on add nodes, or change orientation

[turizoft]

Hi,

I got this issue: When I try to add nodes using the addSubTree method or change the orientation of the tree, it suddenly expands way too much and its unusable, as you can see in the attached image. I'm following the addSubTree demo, basically I don't change too much but the appearance of the nodes and edges.

Anyone knows what happens?

Thanks in advance.
