Tree/ADD potential must be avaiable

[Adrián Mora]

Death[0] don't allow select tree/ADD. If the link is deleted and relink Death[0] allow select tree/ADD

[Jorge Pérez]

It seems to be a corrupted network. “Death [0]” potential should have two variables: its own variable and the one of its parent (“Cycle [0]”) but, at it can be seen below, in the potential only appears the first one.

Please, if you find how has been corrupted the network (how to reproduce this corruption), let us know, describing the process.
