Hi Xangold, I just opened a support ticket on this issue before i found this thread. I have 4 active bots. 1 of which does not have this problem, and 1 that used to work.
working
bot: taxicabunionbot channel: dickiegreenleaf
used to work
bot: stankabot channel: lividust
not working
bot: sk00ntbot channel: hyfr0
bot: daintyb0t channel: missdaintykaty
the 3 not working will whisper if a whisper is sent to the bot first from the user, and the whisper window left open. Note: taxicabunionbot does not require a convo open, it will open a convo/whisper window to the user. verification command on taxicabunionbot in channel dickiegreenleaf: !commands
