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

[Eccezan]

Sunday evening (4/17) not sure of exact time, during CT attempt in fear I was death touched, about 15-20 minutes later I was rezzed and had items on my cursor...Had an 8 slot bag go empty, it was filled with wizard spells. It was most likely a medicine bag because it is the only empty bag in my inventory currently.

From memory, they were the following.

Flaming Sword of Xzul
Plainsight
Manasink
Tears of Prexus (edit: this wasnt in the 8 slot bag, but went missing from another bag)
Pillar of Flame
Manasink
Evacuate
Pillar of Lightning
Disintigrate (edit: just remembered this was in there as well)


I also had a couple non wizard spells that are still in my inventory and did not go missing:

Spell: Convergence
Spell: Forlorn Deeds

Earlier the same evening I logged a few times and regained a few particular items that disappeared initially. These items, also the best i can remember:

Fishbone Earring
3-4 Stacks of Fuzzlecutter Formula 5000

Let me know if there is any other information that could be useful.
