EQEMu Changelog (Started on Sept 24, 2003 15:50)
-------------------------------------------------------
== 05/18/2015 ==
KLS: Changed how fishing locates water to hopefully be a bit more accurate at the expense of a bit more cpu power per line cast.
== 05/15/2015 ==
Uleat: Added check to EntityList::CheckSpawnQueue() to bypass dereference if returned iterator is npc_list.end() - should fix the debug assertion failure crash
