This Super is bugged currently. When using both Top Tree Super and Bottom Tree Super you can throw one hammer and then you’re unable to throw any more. Happened to me twice (and my buddy once) in Momentum Control.
Hello, and thank you for your report. Bungie is aware of and investigating this glitch.
