I've been experimenting with the 'Custom Ticket Fields' app, and trying to get some custom fields setup, since we have several departments that will be using Freshdesk.
After I setup this app, the 'Group' default field disappeared from the Agent ticket form, and the fields from the Customer form won't update.
Further to that, the app itself stopped working entirely. I suspect due to the weirdness with the forms. Even removing the app doesn't fix the default fields being missing.
