Bukkit

Hey there. I've been using this plugin for a while now and just recently have started having problems with it...

You can join the game fine, the start works fine, and everything works. But after the first player is killed, the scoreboard disappears and doesn't come back until the next game, you no longer receive the "redstone" lives in your inventory (they fall to the ground and collect there), and the console gets spammed with error messages (none of which I have at the moment but I can send them if you'd like). I'm on Spigot 1.8.8 and whatever the latest version of the plugin is. Do you know why this is happening? This is the only decent OITC plugin I've found when searching and I'd really hate to not be able to use it... Thank you.
