I think I know what's causing freezing issues with TB teams...
 

For some odd reason I couldn't figure out why this one single TB team wouldn't load. I finally got irritated and deleted one of my 12 teams and then noticed that I still in fact had 12.

So, I swapped the team that wasn't working with one of the other teams I wasn't going to work and now that team that hadn't worked all day suddenly works.

I think there might be a glitch where TB thinks you download more teams than you're supposed to and picks one not to load.
