Items disappearing on multicraft server

[Blood_Raven6934]

mod items disappear when used or placed. If i say put down a piece of marble it will stay there a second then disappear with the rest of the marble in my hand. Multicraft doesn't allow for the launch.bat would that cause this? I change the tekkit.zip to craft bukkit, that didn't work and i have installed and re-installed many times. Any suggestions or fix would be much appreciated.

Wait... If you're replacing Tekkit.jar with regular CraftBukkit, then it won't load Forge, which in turn doesn't load the mods, hence why you're getting those behaviors. The server doesn't recognize those items, then tells your client that they "don't exist" which causes the items to disappear.
