It only seems to work with only one of my channels, be it the bot handling multiple channels or just that one.

channel-mappings {
            "420114396313026560"="#GriefPrevention"
            "341448913200349203"="#MLG"
            "420118648418467840"="#ROBOMWM"
        }

Results in only the #MLG channel being properly bridged.
