Suppose I have term A with children B and C where the children have a 550 tag
with broader indication to A.
If I go to record A, the tree is built showing B and C.
If I add a child D to A, the tree for A is not rebuilt but still showing the
old situation.

A related problem:
If I change term A setting it to a be child of B with a 550 (which it obviously
not is), this cyclic relation will trigger deep recursion. Resulting in a
gateway timeout and a process eating up resources..
