Missing uniosun student reappears says mmm loss made him hide

I think there may be some confusion here. As a conversational AI, I'm not aware of any specific incident or news report about a missing student from the University of Ibadan (UNIOSUN) reappearing and claiming that MMM (Mavrodi Mondial Moneybox) losses made them hide.

Could you please provide more context or clarify what you're referring to? I'd be happy to help you understand the situation better or provide information on the topic if you're interested.
