Also seeing this, with today’s update (10-Feb for 12.0.1); seems to be Blizzard-native Lua code, no 3rd party add-on.

Vortimer, maybe you have figured this out by now, but I had this exact same issue. What apparently happened for me is that some of the class / talent changes really screwed with the settings I previously had for my Cooldown Manager. After I removed and then replaced a bunch of cooldowns / buffs that I was tracking with the Cooldown Manager, it completely fixed the issue.

I had not isolated this issue to the CDM (thanks for the workaround!), but that’s still on Blizz to fix. :frowning:

Edit: Confirmed that it’s the CDM. I also removed all the “Essential Cooldowns” and “Tracked Buffs” then put the essential CDs I had before back into the tracking box; no more Lua errors.

That seems like a very obtuse ask of players that don’t come to the forums, so Blizz still should fix this.

Totally agree - it took me a while to figure it out.

Came here via Google, can confirm even with no addons this pops up. I thought it was my dark/skin addon, but it all started about 2-3 days ago. It seems like when ure in the group finder u get these.

Been getting them when doing the raid and they leave the lfg tool on during bossfights its really annoying.

On my feral druids its also erasing my combo points bar sometimes when I die such as on Dimensius fights.
