I kept an eye on it, most of the time it just works as it usually does. But I had the same issue recently when I voted already. It started the timer for 1 second; then it suddenly got back to 3 kicks. The person who wasn't voting yet was kicklynched so no vegs for anyone.
similar bug happens to me. the kicks go from 3 to 2 to 1 and then the timer starts, as it should, but then around 7 seconds to go the kicks go back up to 3 and the timer disappears. not sure but i think it only happens when i haven't voted although that might just be because otherwise i don't notice it. not sure how to replicate it. may or may not be what sherekhan is seeing.
