i have a few bugs and missing things here :

1. There are no Sentry upgrading progress in the TargetID which annoys me when i am playing engineer
   
2. No Medic's ubercharge percentage when aiming at the medic (it shows up when getting healed)
   
3. When i can't afford metals for the building other than sentries, it will show up as sentry (literally unplayable)
