Missing an astronomy table and 3 merlin trails

[copper berry]

I know i'll probably just have to ride around my broom casting revealio to find the merlin trails that arent marked, but is the astronomy table a common bug or is there a fix?

[devout lark]

no, they are in hogwarts

astronomy table is near the passageway to the closed herbology corridor. The three merlin trials, I'm unsure about.

the main recap does not include hogwarts, I think
