I'm having a problem with Quentin's Quests (https://subeta.net/quests.php/quentin/finish). I've got both the items, but I keep getting "Error - you don't have all the items required for this quest!" This also happened yesterday. It gives the error maybe one time out of three quests. All the other quests are working normally.

My operating system is OS X El Capitan 10.11.6. and I'm using Chrome.

I've had that happen with quests, but this was different. I double-checked that I had the items, and hit "finish quest" several times. Lag issues are usually resolved when you refresh the quest, so I'm thinking this is a bug.
