oh I did notice a crash when I was trying to fix my sticky piston door. Maybe that's it? if U get a chance, just take those doors down and see if it's fixed. There's some redstone under the front entrance. If not, i have no idea.
I can log-in for about 1 minute, then the server goes down. I thought maybe it was something I built, but other people are experiencing the same issues it seems. Keep us posted Rico.
