Whenever I view a post that i have already favorited, the button still shows up as '+Fav' instead of '-Fav'.
As a result, when I click the button, 'Error: An unexpected error occurred.'

Same, except a post for me is randomly out of order and when I favourite more, it stays in the same place and gets pushed back by newly favourited posts.

Thats because favorites are now sorted by post-id instead of when they were favorited. So older posts that you find and favorite are gonna be thrown in the middle of all your favorites somewhere.

And it especially doesn't work when I can't specifically choose which of my favourite posts I want to display on my profile. I could (somewhat) pick which posts I wanted to display without issue, but now that doesn't work.

Never mind. They fixed it.

I have that bug with a post. Can't add it or delete it from favorites because when a try it an error appears saying I already favorited that post.

If you find that post during a post search, you can use the mode bar just below the search (Ignore the arrow, that's for something else) to change it to "Remove from Favorites", then click the thumbnail to remove it.
