Expected behavior:
When replying to a ticket, the e-mail search is used and a recipient is selected.
Actual behavior:
After a recipient has been selected, the interface reloads and I come to the dashboard.
However, the problem only occurs with certain e-mail addresses.
The error can be rectified for a short time by deleting the browser cache. Until it occurs again.
