Chests.. corrupted?

[Scintille]

EDIT - i should have mentioned it earlier - everything happened on TnFC server
EDIT 2 - i left chunks for a couple minutes, that didnt help. It also "corrupted at least one barrel. I logged off for a couple hours, still had this problem

I was in my "home", creeper exploded near chests. I survived the blast, landed a few blocks from original place. but then for me it was looking like i was alive, was unable to move, when tried to use chat i got the "Cannot send chat messages" error. And in the chat i saw my death from fall damage. After relogging, i saw this


All chests, that were close to blast area turned into empty oak chests. i tried warping to spawn, waiting for chunks to unload, and coming back, relogging. nothing helped.
I had almost all my stuff in those chests..
Normal creeper explosion can only destroy chests, content should drop as usual..
