During the Heroic Mythrax transition, while Mythrax is casting Xalzaix's Awakening, there is a requirement for players to remain spread but the proximity window disappears. Once P2 is complete and P1 is active again, the proximity window reappears and displays correctly.

What steps will reproduce the problem?

1. Heroic raid
2. Occurs every pull

What version of BigWigs are you using? (Stating 'latest' is not useful)

v120 (10/08/18)

Do you have an error log of what happened?

No

Any additional information? (example: WoW language if not English) (Attach screenshots here if available, do not link externally)

In the Mythrax script file I can see where the proximity window is opened and/or closed for certain abilities. I have not tried to manually change this file locally for testing. I believe the spell ID for the transition phase is 273810. Would adding the following line to the function for Xalzaix's Awakening work?
self:OpenProximity(273810, 8) -- Xalzaix's Awakening

Thanks for reminding me to fix this!

Ha! No problem. Thanks for the quick response!
