When creating a new node and selecting a term from HS the node is saved instantly.
I have a taxonomy vocabulary with Countries / Cities.
Upon selecting a parent term (country) i.e. Russia, it instantly shows me the Cities i.e. Moscow, St. Petersburg but the node itself is instantly saved. If i have any other fields that are compulsory, it will keep me on the editing page but pops up the warnings that i must complete the remaining fields. If i don't have any compulsory fields left to complete it will simply save the node and redirects me to the "view" page.
I don't know if this is a bug.
PS: Excuse my english
