After the purchase of the battle pack and accepting items from the Battle Pack Promotion mail, I got the specified amount of energy, coins, but nothing else.
A link from the support page ( https://www.spiralknights.com/support/#mail ) at the top of the forum redirects me to an empty page.
Any suggestions?
