Greetings, Smashington!
Thank you for posting your concerns about the new targetting modes. I can understand how frustrating it can be to be unable to target players when trying to cure other players. Just for further clarification, though, can you please state which targetting mode have you experienced this trouble in? It would be a great help to us if you were able to provide this information. Also, here are the notes for the commands for the different targetting modes, just in case this information proves to be helpful with your situation:
