Game Mechanics: Beginning a song, and then sitting

[Pescador]

I've noticed that as of the lastest patch, when I begin my heal song and immediately sit down, the song won't finish casting.

Before the patch, as well as from what I remember from classic EQ, you could begin a song, immediately sit, and the song would pulse wen the casting was finished.

EDIT: This also occurs when you loot a mob before a song has finished casting; it interrupts the song.

Strangely, you can still sit or loot once a song has already pulsed once, but on the first pulse, it'll interrupt.
