Yay... bukkit semi fixed this with a patch from a guy, but it still happens a tiny bit and sometimes still glitches out server side (I logged in and got pwned by someones grinder one day ) This is awesome news.
Mojang did a damn good job picking these guys to be a part of the team. I don't know them on a personal level, but their impact on the community has been quite noteworthy since I started playing Minecraft.
u serious? yaaaay thank you Bukkit Team we all love you dearly! Why cant Mojang think of these things
