Hi Luxury_a
I also experience this issue.
It used to happen when you had missed an upgrade. For whatever reason, your PC did not download it. Often it was blocked by your antivirus
So if one player had the upgrade and you had not, you could not see their profiles if they wear the new item.
In rooms, if they had a new pose and you did not, you would see the the default T avi stance.
The only way to ensure you have the full upgrades, is to uninstall and install the game again.
Please let us know if this resolves the issue, if not please report to Achat Support and keep us updated on the progress.
Thanks
