EDIT: The second issue is now a non-issue. Must've just been that server, as I haven't been able to replicate that problem so far.

So I recently updated to the current patch and headed to Docks to find the tyrant blockers because I was curious. I couldn't find any on Freeroam mode, so I figured it was only on TDM. I hosted a local server and hopped on, and was automatically put to the human team. Except that I couldn't select a single class. Above each one, it just said UNAVAILABLE.

Any ideas what is causing this?

Quick Edit: On Freeroam I had no issue changing classes.
