Help

Since the recent update with the marketplace, I have notice that some of my houses that were saved on the gallery and onto my showcase are no longer there, this also includes part of my sims family who are no longer there either not even in the not placed In world category, some of my houses on lots have vanished also,

im no professional but had a decent amount of downloads on these builds and I’d like to know where they are as they are no where to be found, 

if it helps I’m doing this on a Xbox,

regards
