This patch is based on an old work of Koani and working like a charm (months of tests on my friends server). I updated again for mangos and I think to shared here... Patch for Mangos Relase Date: Sat Nov 12 21:24:50 2011 +0100, [11846] Changes to default target selection. Assign a new leader when current leader is logged-out (time for leader relogin is configurable). Also fixes: * Some instance resets, when leader crash client, etc... (no removes member on logout) * Member out of range is logged group cant summon it. (because group member status is now updated) Write by me and based on Koani previous work http://pastebin.com/EnrZnsyp Cu and thanks for review my code
