Missing: Stack of Diamonds and possibly other things

[clawstrider]

I am missing a Stack of Diamonds, and possibly other things from my precious chest.
Co-ords: -419, 882 on level 66.
It has always been locked, with only Turtleman918, Davioo and myself having access to it. The only explanation I can think is it got unlocked by lwc in the update.
Any items taken out by someone other than Turtle, Davioo or myself is theft, and I was wondering how to get these items back.
Thanks.

26 diamonds was the only thing taken from it the day of the compromise (we were only compromised for about 4 min before we shut it down) You got those 26 diamonds back.
