It seems to cycle through all the puzzles, but doesn't actually solve them.

I presume there's no keystone support either?

Hello, you can use lua code like: 

    public WoWAreaTrigger CorrectTile =>
    ObjectManager.GetObjectWoWAreaTrigger()
    .Where(u => u != null && u.IsValid && (u.SpellID == 219246 || u.SpellID == 219262))
    .OrderBy(u => u.Position.DistanceTo(ObjectManager.Me.Position))
    .FirstOrDefault();

    public void DoQuest()
    {
        if (!ObjectManager.Me.HaveBuff(219247)) return;

        var tile = CorrectTile;
        if (tile == null) return;
        var loc = tile.Position;

        if (loc.DistanceTo(ObjectManager.Me.Position) > 1.5)
        {
            MovementManager.MoveTo(loc);
        }
    }
