Had my garage do a little disappearing act. All of my cars are history.
I've done a little research and I see that it isn't exactly uncommon, but even though R* says they've resolved the issue in a prior patch, this happened to me well after said patch (I was off XBL for about a week, came back and poof).
Not broken up about it or anything, and I'm a cheapskate so I only lost maybe $50,000 total in vehicals, but my primary concern is whether this will happen again.
I've made peace with the fact that I probably won't see the rides again, but can anybody tell me if I still have to worry about another event like this in the future and/or is there any real way to prevent it from happening again?
