I have the stable version 1.7.0 of osTicket updated from 1.6ST and when I try to update it, for example to 1.12.5 or 1.14.6. the person who has the problem, therefore the user as defined in the new versions, are not maintained and when the update is carried out a random user is taken and is repeated for example 20 times in tickets that do not belong to him.
