Is this a bug?

While running dungeons and skirmishes to fulfill the "Kill or Treat" mission, I couldn't help but notice that anybody in the party could grab up the Liars Charms and Sweet Treats regardless of who killed which npc... and it would only count for the player who picked them up first; not the whole party. This became very disheartening very quickly because I just couldn't make any headway. These drops apparently don't behave like Waukeen's Coin Purse where everybody gets to pick one up. And so, I decided to stop queuing for groups and just go solo. My question is: Is this a bug?

For the record, the "Kill or Treat" mission can be done solo. I did it... after six hours of non-stop game time. This is not a complaint. I'm enjoying the event so far. Just asking.

Side note: I've experienced random dismounts in the Well of Dragons. I would have just finished fighting a mob (or a dragon in a run) and as I attempt to mount and leave, there is a booming sound effect and my character is suddenly dismounted but with no damage. I will attempt to remount and it happens again. Eventually, I have to run a distance from the combat area before this stops.

There are no attacking npcs and my character's stats appear normal (not poisoned, paralyzed, stunned, etc.).
