thats mean u need to have the updated pull request that already merged with latest rathena commit.
fix the conflicts when u git pull and should be okay.
git pull origin master <-- this will pull all latest git (if u clone from rathena before).
in latest commit most of skills database already converted into skill_db.yml
1. dont add view equipments permission to normal accounts.
2. maybe theres file that didnt added yet/conflicts in your files. Example sprite, iteminfo, etc.
//In this script's original state, a "World Boss" will
// spawn in a random location after 10,000 monster kills
// every 4 minutes past the hour.
Does it mean 10,000 kills for each character or count from all players ?
