@sacrophyte Special events like that are not planned in the near future. But if you use a scroll to unlock an expansion the singleplayer mode will be unlocked, too. Using one scroll gives you access for 24 hours for that expansion.
Most of the control options are covered in the tutorial - nevertheless I've forwarded your suggestion to the team. Thanks!
@Leenylein1990 Danke für die infos. Der Patch heute sollte das Problem beheben.
