Forum:Cheats giving me problems

Ok so I get that cheats are supposed to help you out and make the game easy. It does the opposite when I play though. I got to Mexico and had activated cheats. It told me I could still save so I thought, huh I can stand in front of a bear and pwn its ass and it cant do shit about it. So I activated the cheats and saved it in Mexico.(My last save was at rathskeller fork i had not done any side missions or main missions) Then I turned on the game the next day and I was back at rathskeller fork! It took 2hrs of creepy ass hunting in tall trees to get to mexico! I hated that shit. I have to do it all over now=( What I want to know is will cheats allow you to save the game in undead nightmare I need to know this cause I want to try some cheats or beat the game.
