I just recently noticed that the tincture seems to be useless. I know it USED to have a function! I used to use it every two or three times I was in Zombie Fights. It would say APPLY Tincture, do the animation, then as I walked, it would say in the corner YOUR WOUNDS FEEL BETTER or something like that, to tell me that the tincture was working to make me better. Now I can APPLY the tincture just fine, but it no longer ever gives me messages to tell me that it is working.
PS.
Do the Vitamins give any advantage?
