Free Stock Glitch?

So logged in and it said on Card. “Your Free share of Zynga was added to your portfolio, invite more friends to get more Free Stock.”

I’m like I didn’t scratch a Free Stock thingy, in awhile do they just choose for you now?

But then I go to “Past Invites” “Joined” and on March 8th the 1 share of Zynga is from someone I had already got the 1 Share of Free Zynga Stock from Way back on January 7th according to my Excel spreadsheet, I keep track all transactions. I had since sold that stock and re-Invested it in something actually worth something.

So anyone else had a weird glitch like this? It did NOT add to my Portfolio Value and it’s not showing a CURRENT Zynga stock on my Stocks, so I didn’t get it again. But it’s on my Card right now and showing joined March 8th in Invites.
