If medic is out of ammo for his primary weapon, he switches to medigun and tries to heal it's enemy. Instead, he should switch to his melee.

If medic is out of medigun ammo, he pulls out his primary and starts to shoot whoever he is trying to heal. It happens rarely under certain circumstances that I'm unable to reproduce. I think that medic NPC should have infinite ammo for his medigun because this is how it works in the actual game.

Also, If NPC medic happens to use his ubersaw, he doesn't get any uber on hit.

Huh. That's actually a hilarious bug, but I think I've also encountered that once or twice myself.
