Infinity ham disappears from my inventory

[PedroUFirmani]

Sometimes when im playing and I open my inventory, my infinity ham just disappears. Sometimes it temporarly clones itself when i get it of my hotbar and put it on my inventory but soon the clone disappears, is there something i can do about it?

Looks like a client lags. It's not an issue of Relics.
