 Bug Fix
- Fixed a bug that prevented players with a full inventory from receiving their reward for completing a Halloween quest. Players who have already completed these quests are now able to replay them in order to receive any rewards they missed.
 Guild Wars Wiki notes
- Better You Than Me and Double Your Pleasure and RUN! are the Halloween quests that are being referred to. Unlike the Wayfarer's Reverie quests update, accounts that have already completed one or both of these quests prior to this update can complete them again for a maximum of four Ghoulish Accessory Tokens.
