Revision 177, 10.2 kB (checked in by yumileroy, 17 years ago)

[svn] * Avoid access to bag item prototype for getting bag size, use related item
update field instead as more fast source. source mangos.
* Further reduce of DB access in guild handlers.
* Multi-locale DBC extracting - source Foks

*** Devs not responsible if all your player items drop to the ground and get eaten by ants or rabbits.. or some kind of wierd ant-rabbits..
