Increase max lvl problem

[Daemon01 0]

Hello, i ve increased max lvl to 350, everything is working fine serverside/clientside, but i have 0 drop at any level.The mobs are set correctly in the db(i use sql).Even if i change them to lower lvl like 200 and i lower my char level, it s the same, no drop at all.I checked mob_drop_item and the database many times, everything is correct.Does anyone know what could be the cause?Thanks
