creating a graph from a node will cause the node to error on selection

[Plagiatus]

When dragging a node from the hierarchy to the Internal (in the example I uploaded I used the "space" node), that node then throws errors when selected in the hierarchy until the hierarchy is re-rendered (either by selecting a different graph by folding/unfolding the parent node).

Also, a possibly unrelated incident: When I did the following:

1. turn space node into graph
2. select node
3. hit delete key (notice that it didn't work)
4. attempted to modify the transform attributes with arrow keys
5. loaded the space graph
6. attempted to modify the x transform attribute with arrow keys

At this point FUDGE froze. However I cannot reproduce the issue, but I thought I'd mention it.
