FYI - They changed the way forum posts are displayed and took me a while to figure it out.
Make sure that under your original post, you set the display option to “OLD” so the oldest replies show in order if you want to preserve the old forum feel.
To be honest i like the new forum interface. Of course some people may not like it it’s a personal preference. 
@Samuriko Unfortunately it does not keep the setting. Even if you reopen the same thread in a row the default is always “Top” and you have to select it every time to “old” if you want to read it chronologically. Very annoying…
Then we would need a classic option.
I click some posts and I do not see all of the comments anymore.
It’s super annoying to me.
