I was trying to set the "item_rate_adddrop" setting in the "conf/battle/drops.conf" file, when I noticed something strange.
In spite of keeping the drop rate at 100%, I wasn't getting any drops from the 2 cards that I tried.
Thats when I noticed this error in my mapserver console -
This error is created only when I login a character that possesses these cards.
Any suggestions on how to fix this?
