Arch, you have no evidence that Lantz is lying. You are just assuming it because you can't believe he's capable of miscommunicating it which frankly seems like a bizarre assumption given past evidence.
Despite what you might think, people don't always get things perfectly worked-out in their mind immediately, or articulate that perfectly first time around. I know my characters are still developing somewhat in my mind, because I have never written them before now. And, further, I also know that I overlook things that my character would remember, because they happened ICly a few hours ago but OOCly months ago.
Even in that case all this still applies, as this castle is a bullshit testiment to a single Sue, and there's no indication of miscommunication. I know that lantz can miscommunicate, I do it myself occasionally, but I can't believe in this case that miscommunication could lead to such blatant retcons, bullshit, asspulls and dickery. Oh, and Mary Sue wishfulfillment.
For that matter, Lantz's actions within the RP have been less than stellar, often glorious mary sue glory hogging attempts along with asspulls galore. He seems to give not a single fuck about any characters other than his own or their desires, then expects to be accommodated by the other players in having his characters be front in center in everything after IC'ly insulting them. This is the sort of behavior that kills RP's. The fact that his characters are pretty blatant fucking sues compounds this (I ran Satoshi through the Mary Sue limitus test, after reading all the rules, information, and everything I could on him. He scored a fucking 89. An 89. The sue threshold is roughly 50 points. There is no excuse for that, especially in a fanfiction character that acts the way he does. Satoshi is such a fucking blatant sue it actually slightly hurts.)
Lantz also refuses to take criticism for any of his actions, accept responsibility, act like a fucking adult, and considers any pointing out that his characters are horrible horrible people and sues to be an attack on him personally, even when it isn't.
Mike, I know you like Lantz because he stuck up for you on BL, but that's no indication of his being a quality writer of any fashion.
