Nice to see this updated for 3.x although it doesn't seem to be working correctly for me.
To clarify I have it reporting to a custom channel and the "Testing Channel Printing" works ok. But when I actually cast misdirection either on my pet or another raid member I don't see any bars or outputs in the chat channel.
I have tried with both migrated settings (which will save me some work later :D) and with a clean sheet.
I have checked and that file and path does exist ;o
Well if CBH didn't get packaged, that would explain the problems with not seeing textures or fonts on the config screen, and would likely explain not seeing timer bars. However it doesn't explain not seeing the message print in your channel.
Edit: Oh I see, I goofed on the embeds.xml, I'll commit a fix for CBH. Maybe that will fix everything.
Latest alpha, this should hopefully fix the issues with it silently failing to load the addon. I forgot to copy a local variable over from the 2.4.2 version of the addon, which broke the shared media stuff.
