Describe the bug
Every time when any of my characters start eating, i get this LUA errors

1x [ADDON_ACTION_BLOCKED] AddOn 'WeakAuras' tried to call the protected function 'UNKNOWN()'.

Could You please take a look and maybe find a fix for this ?:)

Best Regards

This is caused by a change Blizzard did in 8.2.5, but didn't bother to put on the PTR nor into the patch notes. Addons can no longer send say messages outside of instances, thus any aura that tries puts out a error. That error is tracked in #1733.
