I've just been on GTA 5 online on my character. Both me and my partner have our own characters (on the same profile though) and when I had finished playing, he swapped to his character. He had an apartment with a 10 car garage as well as a separate 10 car garage but this time when he went on to his character they'd vanished and now he only has an apartment with a 6 car garage, no way near where his original apartment was. He rang the mechanic and most of his cars were in storage.
Has this happened to anyone else? Nothing had changed on my character. I still have a 10 car garage as well as an apartment with a 10 car garage.
