perhaps you should clone a new version and do a folder diff comparaison to see what was changed :
Assuming your current serv is in
base/myserv/
cd base/
git clone https://github.com/rathena/rathena.git newcopy
diff -ur myserv newcopy
If your rates are default but you changed the exp table to make it higher than default, I would suggest putting it under Medium Rates as "Custom XP Table" or something
