Geez guys, take chill-pills. Grimper has every reason to desire that his hard work be restored. He also needs to acknowledge that neither he - nor any of us - actually have any real "rights" on the server - regardless of whether we've donated or not. This ain't a political campaign, and donors don't have more of a say in determining what the recipient does or doesn't do with the money (read: time) they have. Qaz is maintaining the server on his own bill, regardless of our contributions - and if he desires to shut everything down at a moment's notice, he certainly has every right to do so.
Requests are fine; repeated requests are ok if a decent interval has passed between them; constant requests & demands are not ok.
Understand this: Minecraft != life. Life takes precedence to video games, especially for those of us who have serious responsibilities, such as a job, a family to feed, etc. I spoke with Qaz the other day, and he doesn't sound like a responsibility-free teenager, but a grown man with all that entails.
So: the chunk errors are a known problem, affecting the server as a whole (although yes, affecting some of us more than others). Qaz will get to fixing them when the time is right for his life, his priorities - not ours. Since he is providing this server to us at HLP, we certainly can - and should - speak with him about any related issues; it's his choice to maintain this thing that inevitably comes with maintenance issues, after all. But let's be somewhat mature about things here - tell him what the problem is, and stop griping about it... recognize that he'll try to get to it when he can.
