140 * 2) The channel is desynced. That can STILL happen with TS
142 * Now, the old code roger wrote, would allow the KICK to
143 * go through. Thats quite legit, but lets weird things like
144 * KICKS by users who appear not to be chanopped happen,
145 * or even neater, they appear not to be on the channel.
146 * This fits every definition of a desync, doesn't it? ;-)
147 * So I will allow the KICK, otherwise, things are MUCH worse.
148 * But I will warn it as a possible desync.
