Wake me up when a game drops the option to +2 and -2 on the same turn, as though they can override a previous vote. To elaborate, when I do a -2, someone else can do a +2 on my vote and do a -2 on a different vote, effectively nullifying my vote while they could make a move. You could say that I could do the same, but that would mean the other options (+2 only and -2 only) are meaningless despite being able to be done.
