update! is simply calling transact! for you just the way you called it
initially so i don't see how it could be the problem, here is the source:
(defn update!
"Like transact! but no function provided, instead a replacement
value is given."
([cursor v]
(transact! cursor [] (fn [_] v) nil))
([cursor korks v]
(transact! cursor korks (fn [_] v) nil))
([cursor korks v tag]
(transact! cursor korks (fn [_] v) tag)))
