I am unable to upload some of my Bureaucrat charm nanos. What can I do?
This is most likely because the nano's have the same 'to cast' and 'to upload' requirements. To upload a charm line nano you need to meet the specific conditions that would otherwise allow you to cast that nano. Among other things this means, "Be in a team if its a team version".
Other necessary requirements: 1) Target something or someone with a low enough psychic; 2)Have no other charmed pets; and of course 3) have the needed nano skills and Specialization level (if required).
