I wanted to raise the friendship of my Eevee so it could evolve, but I saw all my shops were sold out! I don't know what caused it, but I think it was because I set the time back to my birthday so I could catch a Sealeo in winter. But I don't know how to fix it! Can someone help me?
if you change the time on your ds you have to wait 24 hours of real time before it will restock the stores. this is in there to keep people from constantly changing the clock to gain extra items or other shop benefits. you can bike around a lot to raise the friendship of your eevee if you are really impatient. if you go this rout it helps to have the soothe bell, I believe it is in nimbassa city
this also happens to secret bases in oras.
