Attribute is not gained when under Controlled Metamorphosis

When an attribute passive node is under the ring of Controlled Metamorphosis, it doesn't grant any added attributes. This happens both when the node is not connected to the tree (and thus only allocatable through Controlled Metamorphosis), and when the node is connected (basically we lose that node if the ring falls on it).

(sorry steam only keeps this for 2 days so video will expire soon, but the bug should be reproducible)
