that script uses custom items
if (.@class_type == 1) { set .@class_type$, "Swordman"; set .@rand_bonus, rand(25000,25017); } else if (.@class_type == 2) { set .@class_type$, "Mage"; set .@rand_bonus, rand(25018,25037); } else if (.@class_type == 3) { set .@class_type$, "Thief"; set .@rand_bonus, rand(25038,25058); } else if (.@class_type == 4) { set .@class_type$, "Archer"; set .@rand_bonus, rand(25059,25080); } else if (.@class_type == 5) { set .@class_type$, "Merchant"; set .@rand_bonus, rand(25081,25102); } else if (.@class_type == 6) { set .@class_type$, "Acolyte"; set .@rand_bonus, rand(25103,25126); }.... delitem 30000,1;all these item ID are not available in our current SVNwe only have those in the ID range 4700~4899
