Exception from IRC API: Trouble processing message: Contains non-registered mode: r

[Brottweiler]

While troubleshooting https://github.com/zachbr/Dis4IRC/issues/75 I noticed today this error, and I am not sure what it means. I am using ngIRCd with anope services if that is relevant.

[19:14:41] [default] [INFO] - Bridge initialized and running

It's likely that this is just a warning that a channel mode isn't recognized for whatever reason. I believe it's harmless but I've pushed a commit so that these messages will provide additional context information in the future.

If this is something you're seeing regularly, please grab the latest build, send me the stacktrace associated with this, and I'll try and look at it further. Thanks.

If I understand my own code correctly this is from the IRCd not sending r as one of the possible channel modes during ISUPPORT, and then later sending it here.
