Hello specter folks, I get a weird error in prod and I don't know what I'd causing it:

Omar:
No implementation of method: :get_cell of protocol: #'com.rpl.specter.impl/PMutableCell found for class: clojure.lang.Var$Unbound

What can be the cause?

@richiardiandrea: are you using 0.12.0? (see https://github.com/nathanmarz/specter/issues/132)

Oh, it looks like my problem exactly ;)

I confirm that 0.12 fixed it, thanks @codonnell

You're welcome.
