I did notice an issue on the build from about a week ago (the second last one), I saw it on a client’s system. I have departments for takeaway and delivery/collection, ticket types for takeaway, collection, delivery. Client took an order for collection (in delivery/collection department), after closing ticket, then clicked takeaway department and started new ticket. Default on takeaway department is takeaway ticket type. However, “last used” collection ticket type got used on that new takeaway ticket. I verified all settings and all were correct.
I also took a backup and tested on my system, but I had the latest build of v5.2.11 (this is the same backup I sent you @emre today by PM). I could not reproduce this issue on my own system, but I could reproduce on the client’s system.
I was meaning to test more before mentioning but since you are ready to release, felt it best to mention now.
