If I remember correctly on a three way picarto stream with Barnel, Scappo, and Daxor, I think it was a week or two before mad max came out.
That Most of the artists for tail heat went MIA for some time without any notification from them. Twinkle-sez had a medical reason why he was MIA, most of the other tail heat artists didn't keep anyone up to date about there status or if they are going to return later but no response from anyone.
And so Barnel and Scappo had to hire other artists on for tail heat cause they were considering to shut the site down at the end of last year, since there were barely any updates for tail heat. But it seems that tail heat is doing fine now, but as to how that may be we'll just have to wait.
