I'm not sure how it's related but I get the following error when clicking on the "Guild & Communities" icon while in a raid:

[ADDON_ACTION_FORBIDDEN] AddOn 'BossesKilled' tried to call the protected function 'GuildControlSetRank()'.

I get the same error.

1x [ADDON_ACTION_FORBIDDEN] AddOn 'BossesKilled' tried to call the protected function 'GuildControlSetRank()'.

I can't reproduce this and the addon doesn't have anything to do with guilds so I'm not sure why this is happening.
