Roleback issue

[drakenbaas]

So I just unlocked the desert island and I went to fight the zombies, my sword was low on durability and I went back to my chests to get some cobble and repair it. Ones I got my cobble and went back to the "hub" my inventory got rolebacked and the 3 zombie spawners and a few more items were lost/rolebacked.

I do not have proof of this happening and my IGN is drakenbaas, I'm the only one on my island and happened recently.

I hope someone could help me with my issue.
