I was nearing the end of the Dry Dock Jumping Puzzle and then I briefly lost server connection. This resulted in me losing my milestone buff and the Skirt modifier I had paid for. This meant I I couldn’t loot the chest :-(
Food and banner buffs stay on the character when logging in and out, so why doesn’t a buff that has a 24 hour timer on it? Given how long the JP is, this seems like a big oversight or design to grief players.
