Tree Creator Null Exception

Hello,

I'm editing a prefab which was originally made with the tree creator. I was doing my business when I noticed that the tree was no longer updating after I changed things. Upon investigation, I found that the tree creator script was throwing null exceptions when I deleted specific tree nodes (branch groups), which would break the tree. I'm looking for a fix, or to be pointed in the right direction :-)

Repro steps:

1. Create a tree that has a Branch Group (with multiple nodes in the group(?))

2. Add a Leaf Group to the end of that branch group (again, multiple leaves(?))

3. Your tree is complete

4. Modify your tree by deleting one of the branch nodes, where there are leaves depending on it

Top of my error dump:

NullReferenceException: Object reference not set to an instance of an object TreeEditor.TreeGroupLeaf.UpdateMatrix () (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/TreeEditor/Includes/TreeGroupLeaf.cs:145) TreeEditor.TreeGroupLeaf.UpdateParameters () (at C:/BuildAgent/work/842f9557127e852/Editor/Mono/TreeEditor/Includes/TreeGroupLeaf.cs:104)

Thank you for your help!
