Another Bug???

[banj007]

I first jiggled the chest to receive the "its locked" message then i thought "i liked jiggling that i will do it again" (im eccentric like that) so i was about to, when i noticed the hand had changed to the pick up icon and i got the book when i clicked. I am pretty sure I reached through some incredibly small crack between the lid and base of the chest.

--edit--

Now im 100% sure i reached through the chest. If you turn on interact mode and move the hand slowly over the circular-looking part you will eventually get the pick-up hand. I have done it 3 times now. I could do it and maybe screen capture or something.
