title: UITableViewCell is frozen (not rerendering with new data). How to fix?
body: <p>Having some issues with a tableViewCell freezing. I have a table view cell with a list of exercises. When I add a new exercise on another viewController, then pop back to this tableViewController that lists all the exercises, the respective cell gets frozen (see screenshot). Then, if I call <code>[self.tableCell reloadData]</code>, that cell never refreshes.</p>
  
  <p>it's weird because if the offending cell is, say, index #4, and I change the data source to only have 2 items, the 4th cell is still frozen. (the first 2 render correctly, the 3rd is blank, 4th is offending cell)</p>
  
  <p>List of all exercises:</p>

  <p>When I change the data in the tableView data source, that cell is still frozen:</p>

  <p>If I put a breakpoint and inspect the tableView, it doesn't say anything about that frozen cell:</p>

  <p>Not sure where to go from here :( It seems to only happen when I insert a row from a different viewController then pop back to this one.</p>
  
  <p>Any thoughts? Thanks <em>so</em> much for any help!</p>
