Sometimes golden cookies won't appear at all for me, even after I've waited the period they're supposed to appear in. I think this only happens when I've started the grandmapocalypse and usually when I'm offline. Sometimes when this happens I can click on a certain part of the cookie and find a golden cookie, as though the golden cookie was invisible. Refreshing solves the problem, but this requires me to have an internet connection at the time. Does anyone know how to fix this? Thanks.
