Plugin not working with >1 Player Online

Hey Bukkit! I've spent a lot of time on my plugin, and when I decided to test it with some friends on my server (Works like a charm with just me), the plugin just bugs out. Here's my code: (Sorry, I like one class and it's long!)

Does anyone know whats wrong? Thanks for the help if you can!

 

TheRealBuckshot Could you provide more information about what is going on? It "just bug[ging] out" isn't a very specific description of what happens.

Also, please, for your own good (and for that of everyone helping you), please change this 300+ line behemoth

Code:

if (number == 30) {
    for (Player all : getServer().getOnlinePlayers()) {
        BarAPI.setMessage(all, ChatColor.AQUA + "There is 30 seconds until start.");
    }
}
 
...
 
if (number == 1) {
    for (Player all : getServer().getOnlinePlayers()) {
        BarAPI.setMessage(all, ChatColor.AQUA + "There is 1 seconds until start.");
    }
}

into this:

Code:

for (Player all : getServer().getOnlinePlayers() {
    BarAPI.setMessage(all, ChatColor.AQUA + "There " + (number == 1 ? "is " + number + "second"
                     : "are " + number + "seconds") + " remaining.");
}
