Where are these gifts? Gifts usually on a 3/4 hour cycle - you can see the countdown to refresh and I see nothing, no gifts and no countdown. Been online for two hours - logged in twice - nothing.
Often they are all taken out within 20m of appearing. You must refresh (F5) your browser to see the next round when they appear again.
Take time of expriry, add 10m or so, then refresh until you see them in the varmint list again. Then go hunting. You will see them.
