When installed onto a forge server, it crashes the server. Most client-sided mods do not do this.

Error:

[19:31:18] [Server thread/ERROR] [FML]: An error occurred trying to load a proxy into maxwell_lt.titlechanger.TitleChanger.proxy
java.lang.ClassNotFoundException: maxwell_lt.titlechanger.TitleChanger$ServerProxy

Try using version 1.1.4, I believe the issue has been fixed.
