I found too that adding a new user after upgrading core/filesystem it's created as expected without any issues. Anyways, if no problem arise I think I will wait until next package update and try to upgrade it but in the event it's totally necessary to upgrade this package seems I will need to do that 'trick' of creating a new user after upgrading and migrating my actual user to the new one. Thank you very much again! Last, wish you all people the best for the upcoming year: Happy New Year! =D
