I have been playing the game for a while now on the revamped survival mode. My character is level 67 with all ten ranks in each of the 7 SPECIAL stat perks. Once I had reached rank ten with my perception I has gone out to collect the bobble head to push my stat up from 10 to 11 however when I did collect the bobble head and checked I found that my Perception read (-)2. I reloaded from the last save and checked my stats to find without the bobble head my Perception read (-)1. This is all wrong. I've looked up how this could occur and found two possibilities. The first one was a debuff caused by concussion (Crippled Head) and could be fixed by re-crippling the head and then healing, unfortunately this did not work. The other possibility is that it was caused by a hunger/thirst debuff. I do recall VERY early in the game (Approximately at level 5) I had grown hungry/starving and thirsty/mildly dehydrated which would have pushed my perception below 0 at the time. My best guess is that the hunger/thirst debuff pushed my perception past 0 causing it to never properly recover. I ask that you PLEASE try to give this bug a fix. You're UFO4P is my only hope at this point.
