Talking to Otoye in Battle for Dazar'alor doesn't display a dialogue option to get to the final boss.

To add to this issue, this behaviour exists in several other legacy raids as well. For example, Sky Captain Swayze in Dragon Soul after Ultraxion, and Thrall after Spine of Deathwing. Another example, the device that lets you "Proceed" after Anduin in Sepulchre of the First Ones also does not show. In all these examples, reloading ui fixes the problem but is quite inconvenient. Can this please be fixed?

Hi!
Please enable "Use WoW's Default UI In Instance" in this addon's settings - Gameplay. It's at the bottom of the list.
The issue is likely a result of unintended interactions between different addons.

Thank you, I somehow missed this setting. It's good enough for my purposes.
