I'm unable to add new Płocieniak profiles anymore. I succesfully created more than ten, but now I get the message:
Error with duplicate ID when creating account for Płocieniak
Unable to create/save new child.
I get this for example when trying to add a child for Płocieniak-7 (Januaria, born 1902). I tried to do the same by adding a sibling for Płocieniak-6, with the same effect.
The same when trying to add a child for Płocieniak-9 (Jarosław, born 1968).
By searching G2G forum I was unable to find any solution for this problem.
