MonoDevelop works perfectly for all my projects except this one [SOLVED]

In the project I’m currently working in MonoDevelop refuses to highlight errors. I have to go into Unity to see what errors I have in my code. I’ve tried resyncing, reimporting, everything I can think of. These projects look identical.

If I make a typo in any of my other projects MonoDevelop immediately highlights the word and tell me what’s wrong. In this project nothing at all happens. So frustrating.

The problem was a name collision apparently. Everything seemingly worked, but I think my class had the same name as an existing class.
