In this part try changing it to the exact rate of what you put in your exp.com
setarray .Modifier[0], // Multipliers for Base Exp, Job Exp, and Zeny rewards.
getbattleflag("base_exp_rate")/100,getbattleflag("job_exp_rate")/100,60;
so for example mine is 8k i did changed it like this
setarray .Modifier[0], // Multipliers for Base Exp, Job Exp, and Zeny rewards.
getbattleflag("base_exp_rate")/800000,getbattleflag("job_exp_rate")/800000,60;
