Oracle 12c: Procedure created but does not exist

has anyone seen this before?

I'm creating a procedure and SQL*Plus claims it has been created and I can execute it, but it doesn't show up in user_procedures and there is no source code in user_source

  SQL> select * from v$version;

Any ideas?

This is an Oracle12c installation with a single pluggable database on my Windows laptop.
