It has been brought to my attention that adventure log commenting has disappeared!
Looking into it more I have found a decent bit of discussion on the OP forums.
Before you worry, all comments STILL EXIST, we just can’t see them.
The wiki devs are working on re-enabling them.
It may be a little while, but they will be back!
For now any discussions should be opened in the forums.
Let me know any other issues you face.
