Game Mechanics: Items in bags disappearing, April 17th Patch

[Pescador]

Just this afternoon about 30 minutes ago i got a rez in Burning Wood, looted my corpse, and had all my items except my lute, which i left on my corpse while I dealt with aggro. Shortly afterwards (still had rez effects so it was only a couple minutes), my screen froze briefly and then I got booted to the login screen. When I relogged, I was standing over my corpse (not where I had been when I was booted) and there were two bags either on my cursor or on my corpse (can't remember), and when I put them in my inventory, they were empty.

Both bags were empty - one light burlap sack, one large sewing kit, and they were in the bottom right inventory slot as well as the one above it.

I can't remember all the items I had, but for sure I had:
In the sewing kit (bottom right slot):
-Kelin's Seven Stringed Lute
-Sharkskin Drum
-Breath of Harmony
-Sionache's Partisan
-Evensong
-Unicorn Horn
-Mask of Deception
-OT hammer

Light Burlap Sack:
-Singing Steel Gauntlets
-Singing Steel Boots
-Gold Plated Koshigatana
-Pegasus Feathered Cloak
-??? (I think I had another item or two, but I can't remember)

EDIT: relogged and zoned a couple more times, and now my lute is in my sewing kit, but nothing else.
