Curious if this was a bug or just got pkd?

I was on my mule in Occlo her names Mongbats Revenge I logged her out hidden in the smithy shop. (this was before the long downtime) when i logged her on earlier today she was a ghost but there was no body anywhere. I lost some tools , ingots, some bod cloth clothes i made , and my black sandles. Im not worried bout what i lost but what im wondering is these few things.....

1. isnt occlo a guarded town?
2. if not does anyone remember pk'n my mule?
3. If it is a guarded town anyone have any idea at all how i died?

4. if i was pk'd whoever killed me im in the market to buy me black sandles back

My biggest worry is if this was some sort of bug to when the shard went down it killed people in certain areas or something.

Any info please post here or ICQ me at 129290595
Thanks
Czarina aka Mongbats Revenge
