Hello everyone. I am trying to make my first plugin an am having some issues. The plugin is called "Clans" and is basically a modified fork of FactionsPro, in witch I am modifying to where the "factions" are called "clans" and the main command is "/c" instead of "/f". (I want my first plugin to be simple of course.) However, when I tested the plugin, the server crashed and I got a crash dump. When I submitted the crash dump at http://pmt.mcpe.me/, it gave error code, containing "ClassNotFoundException". So I was wondering if some more experienced plugin developers could please help me with this.
