I've noticed today that I'm not receiving alerts that I can trick or treat again, even though I'm hitting the make alert link every time. Pumpkin patch is working though, and I haven't been on long enough to notice if zapper is working or not, just as an FYI.
EDIT: This seems to be an intermittent problem. Sometimes it shows, and sometimes it does not.
I've had this problem off and on a lot, and a few times with the pumpkin patch as well though not as often. I haven't had any problem with alerts for the zapper, though.
Not only is my TOT alert not working, I can't trick or treat at all. It's been beyond 10 minutes, I should be able to trick or treat again.
I don't use the ToT alert because there's such a short wait, but my Zapper Alert hasn't been working since they started the Bribe feature. Pumpkin Patch alert seems to be working fine though.
I keep getting an error message when I ToT from anywhere other than a profile. It isn't every time but it is quite often and happens from links in the forums and the random ToT link on the news page.
