H ow long does it take for the store to stock up with new things
evry 24 hours?

but mine isn't doing so anyway to fix this bug

You may find the information in this post helpful. To see which version of the game you have, check the lower left corner of the main menu of the game.

I have .05 version but my stock takes longer than 4 hrs or sometimes more than 8 hrs to restock. I'm not moaning about it, just thought i would let you know. I tried checking my log in LDW file but it does'nt log like the other VV game logs does. It does'nt show whats happening with peeps, restock time ect. Only loadings of the house items ect. Sorry if i've posted this in wrong place.

I hope this helps!

Try refreshing using the r button like Lady told us to do. Sometimes it will refresh my store items and sometimes not.
