I honestly think that outside from his personal life, one of his biggest problems is that he's currently drowning in too many commissions. As soon as he opened the suggestion of taking requests and doing resin molds of his mask, I've noticed so many people on here as well as over on 4chan mentioning they asked about a life sized Miru, a resin this, a custom model that, so I'm not surprised he is missing deadlines. People have not been giving him enough space to even finish the MoUP before they started asking for other things. Is this inherently all his fault? Of course not. I will say the lack of his presence online is a head scratcher but we don't know his home situation. Considering his last update on this topic emphasized connection issues because of storms, I'd just wait a little longer. If you really need to contact him though, RolloutReviews is the best middleman I can think of.
