- Server compatible with the weapons and equip again. (Some Packets were incompatible) - fixed bucket bugs (not all) - Fixed clients getting crashed by wrong Pickups - fixed nearly all mob drops. (Check wheather they are burning is missing Big Grin) - maybe some other things I can´t recall atm Big Grin git-svn-id: http://mc-server.googlecode.com/svn/trunk@94 0a769ca7-a7f5-676a-18bf-c427514a06d6
