Its in old plot, you can play on it by starting new game. Old plot will be deleted, all events, quests and other things will be migrate to new plot in 0.10B
Are there any plans to reintroduce that content?
The way the game is right now is not very enjoyable for me. Its a lot of "work" for little reward. Dialogue for hours without much else.
Dont get me wrong I really like the dialogue, its witty and engaging but you never get a break.
In the old plot the private lessons etc were like rewards or breaks inbetween plot. Now when that content isnt in the game anymore the game starts to feel very slow.
