In red dead redemption all the shops are closed. what is wrong?

ok. here is the full story. as soon as i did that mission where you break that yellow horse with bonnie mcfarlane. i decided to be good and get the duster before i went to mexico. so i spent a lot of my time doing good deeds and doing missions. and after the mission right before the mission you go to mexico with irish. i got peacemaker honor status and earned the duster. after i got the duster i went thieves landing and purchased the bandanna. and headed to mexico. then i beat the story mode. and became jack marston. then i did the remember my family side quest where you kill edgar ross. after i killed him i decided to have fun for once since i did not kill innocent people while i was john marston. i decided to do that with jack marston. so i went to my nearest house and put the bandito outfit on. along with the bandanna which i already had on. bear in mind my honor status is still peacemaker. so then i set out across mexico killing enough people for a 425 dollar bounty. then i left mexico and went to thieves landing and put the duster back on and my honor is still at peacemaker. but i noticed all the shops were closed everywhere. what is the problem. how can i fix this?
