I think there's a bit of a problem with the timer on the Bite button. When I refresh, it bites again almost immediately regardless of what the timer said (ie. a five minute wait is only a few seconds). is confirmed to be having the same problem, so I don't think it's an isolated incident.
I think I experienced the same thing but with kisses, however I have to ask the kissed person to confirm this.
The issue hasn't seemed to have happened in the past little while, but an hour or so ago it was going crazy; I was biting people two or three consecutive refreshes in a row, with no wait time in between.
It very well could have been an issue with the kisses, too, as has said. However, I wasn't paying nearly as much attention to them at the time and would have missed it entirely.
Funny-- I noticed the same thing, but thought I'd just been mis-remembering how much time passed between kisses.
I just checked after seeing this thread and it allowed me to kiss almost immediately despite a 5 minute wait.. I tried again and this time the 8-minute wait stuck. So it seems to be something of an intermittent problem.
Had that issue as well with kisses. Sent a comment to the receiver if any went through.
