Finally, I managed to play the latest beta version over the weekend.
I just don't know how to rename the topic :(
While I remember - the portal next to the brown Orc and the observation tree is not working; maybe it's intentional, but all the others are working except for this one.
The manual recommends reading the signs. One of the signs explains that some portals may not work from time to time :)
I'm a little confused about the quests; it's not clear if I choose one, whether I can choose another after completing it, and if, for example, I destroy the Orc Castle, but I didn't take that quest (although I think there was one in my memory), can I complete it later?
That is, the quest you mentioned as an example can be successfully completed later ;)
