As of CraftBukkit_1.3.1-R01, there is a new duplication exploit. See the video bellow: I was wondering if there is a patch for this, and if not, could someone please make one. Thanks
a plugin could fix it yes, but its a CB issue they will fix this soon! EDIT: maybe a plugin can't do that stuff
A plugin can definatly do this. It is a problem waiting for a CB update because people are exploiting this now. Not next update.
How hard would it of been to tell me this first off. But no, you'd rather be a condescending asshole about it.
If you have a genuine bug in the latest build, report it to the bug tracker on leaky.bukkit.org - security flaws should be dealt with pretty quickly.
