please find the log file attached.

Here is a list of all the mods that the server is running:

i recommend implementing a log which contains a history of which items were contained within which graves.
This way, in the event of this error, or any user error, there is a log of all items what were lost.
this should makeit easier for server owners to restore a players lost items.

Further investigation reveals that the gravestone was broken by a mechanical drill (create mod)

in particular, this mechanical drill was on a train bogey. so it was in entity form.
