From 566a6fb8d0fc35267b43721f7e1802ba3475af3d Mon Sep 17 00:00:00 2001
From: Bjørn Lindeijer <bjorn@lindeijer.nl>
Date: Thu, 28 Aug 2008 18:32:11 +0000
Subject: Added support for being effects through the eAthena levelup message,
 and check whether the being exists before referencing it. Re-enabled proper
 MP bar display. Improved handling of a warp to the same map.
