I don't recall seeing any previous reports of this, but it's a tricky one to definitively answer without seeing exactly what occurred in the simulator.
If it occurs again, could I kindly ask you to raise a ticket with Just Flight Support via the following link: https://www.justflight.com/support
When submitting your ticket, if you could include a brief description of the behaviour you're experiencing, along with any screenshots/videos if possible, then our support team will be best positioned to provide further assistance.
