After today’s maintenance a simple macro like:
/w Dassel hello
It’s not working and throw a lua error:
FrameXML/ChatFrame.lua:4524: attempt to concatenate a nil value
I though it was an addon or something but my friends also can’t.
Please fix

This is breaking addons as well.
Yep. As of today, macros with simple /w messages would not work for anyone in raid. We’ve used these for years to avoid cluttering comms with requests for Power Infusion, Salv, Innervate etc. Please help, ty.

I’m getting “attempt to concatenate a nil value” error when using /s or /y in my tanking CD macro’s.
Yeah also having problems w my macros and add ons.
Confirmed, this is an issue. Current work-a-rounds:
/run SendChatMessage("Power Infusion ME Please!","WHISPER",nil,"PersonToWhisper")
/run SendChatMessage("Click for MAX (2/2) Healthstones","Say")
/cast Ritual of Souls

Nice workaround! Thank you so much for this
Confirmed this. /s, /y, /w no longer working in macros as of 10/24, just causes a brief (<1s screen freeze).
Same problem…
Would be nice to have some kind of acknowledgement from blizz here.
This broke swaths of addons out of no where on a raid night.
All my macros that send a chat message combined with spell usage to alert my raid members no longer work.
Same issue here - all chat macros broken.
Bump, this is really important to not clutter comms
