Bukkit

I'm in a hurry so I'm using the default formatting ff the ticket. Sorry about that.

What steps will reproduce the problem?

1. I wanted to modify the "maxzombies" of a Map in games.yml.
2. I reloaded the plugin.
3. It made this error in the console and couldn't load.
Now when I stop and restart the server, the plugin doesn't load at all.
Moreover, I can't find anymore the lines I edited in "games.yml", they just disappeared.

What is the expected output? What do you see instead?

I wanted to modify the multiplicator (because I think it is the "maxzombies" line in games.yml") of a map without configurating it again.

What version of the product are you using?

ZombieSurvival v3.9 with
Craftbukkit 1.7.9-R0.1
(and soon 1.7.9-R0.2, if this plugin is compatible...)

Do you have an error log of what happened?

Please provide any additional information below.

I have already edited this line for another map without any problems on an other version of the plugin. I hope you could help me.

Thank you for reading this. And very good plugin by the way :)
