A few small notes: 1. Larian support is being flooded with emails on various topics, from shipping issues, to digital extras not being included in some editions, to in-game problems that people run into. Even if their support is working the whole weekend, it could still take days before they manage to process all those emails.
2. Happy Shops (the company handling the shipping) do indeed appear to be quite slow in sending out the emails. Some people reported receiving their CE before they received the email.
3. Even if you receive the email from Happy Shops with your tracking number, it appears that the tracking info on that website isn't updated very frequently... in fact, for a number of people the info didn't update at all until the package arrived at the distribution centre in their own country. I definitely agree that (2) and (3) are handled badly, but I don't think we can blame Larian for that.
