Lost Tokens

I am running a Game, and have a lot of NPCs the characters interact with and take lots of time to find good tokens for them; but recently every time I log in half the tokens are missing and show up as broken images as shown below, and can no longer find them in search. Please help, its very frustrating to plan a game out only to log in at game night to find tokens have gone bad. Using Google Chrome Mircosoft 7

I had this same problem on a campaign I just finished. I just worked around it by having my players ignore them as I could not see them as GM, but they could as players. If you're interested I can send you a link to join Gauss.
