I dont know what you're trying to do but
1288,EMPELIUM,Emperium,Emperium,90,700,1,0,0,1,66,13,64,50,1,17,80,50,26,20,10,12,0,8,26,0x6370000,300,1288,288,384,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
Mob 1288 named EMPELIUM
This mean there is no Mob : EMPERIUM but EMPELIUM
you should do something like
25019,EMPELIUM_OMFG,Emperium,Emperium,90,700,1,0,0,1,66,13,64,50,1,17,80,50,26,20,10,12,0,8,26,0x6370000,300,1288,288,384,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
