I tried BukkitForge-1.5.1-289.jar as well as 288, but it says that it's missing the manifest, and closes out.
EDIT: I didn't know BukkitForge was a mod, I thought it was a server. So, BF goes in the coremods folder, and you launch the normal Tekkit.
MCPC+ 398 works, but I lag out when I log in. Just one user.
I can't run a Tekkit server without the PEX plugin (don't give me heat about PEX), as I use the mysql backend to synchronize permissions across more than one server. There is no other permissions plugin that lets me do that two ways like that, neither bPermissions (which is equally shoddy), and zPermissions (which uses the server's own database, not one I can spec).
There is a PEX Mod on 9minecraft, which integrates PEX into MCPC+, but that doesn't solve the lagout problem.
It would be nice if the Forge team would build off of bukkit, so we wouldn't have to deal with all this.
So, I am still unable to get multiple worlds going. Using Wormhole X-Treme Worlds crashes when I try to create a world.
