My mail and letters from the steward continue to show that there are messages but even after everything is deleted they are still showing pending messages
this is a know bug and has been around for a while now. i was hoping plarium would fix it with this update but unfortunately not.. and sadly i am not suprised
in fact is still not fixed. dont worry in next update sure they fix. devs are working on it but as the moment the bug is only visual and not so important they priorize to solve task more important.
