When reporting an issue, please try to reproduce the issue with just Dominos and Dominos_Config running. Dominos reuses a good chunk of the stock UI, and other popular addons, like Move Anything, like to take control of those parts, too.

Addon Version
You can get this via running /dominos version in game
10.2.30-cata

World of Warcraft Version
For example, Classic, Retail, PTR, Beta.
Cataclysm Classic

The Encounter Bar (shows Alt PowerBar from what I can tell? for when it shows up)
I have saved to a specific location (center bottom closer to my actionbars)
The move overlay at that location with /dominos config so it doesn't seem to be a persistence issue.

Unexpected behavior.
Regardless where it is saved it pops up at the default location when it shows up during fights.

I restored a line that was commented out - in my local copy - and that seems to have fixed the issue (alt power bar showed at the saved location on Chogal with corruption mechanic)

The line in question being Dominos/bars/encounterBar.lua#L78

I have no idea if there needs to be conditional code for other client versions as I don't play mainline.

Thanks. I've put the setting behind a client check because it isn't necessary in retail

The fix doesn't work for me after a death. /rl helps
Version 10.2.32

I noticed the same after some pull on Atramedes.
I don't know if it was due to wipe or Blizzard changed something in one of the recent Cata classic patches.

Also noticed it today while doing dmf dailys

This is real interesting. Which daily shows an alternate power bar. Having a way to troubleshoot outside of a raid would be really helpful.

Okay sorry for my previous too imprecise describtion.
I hope this clearfies it better :)

My Encounter bar is first at the position i defined.
After a death in a fight with an encounter bar, the position is in the middle of the screen.

Ways to reproduce I recognized at dmf:
Exite the vehicle manually at the tonk challenge, be destroyed or let the timer expire (daily: "Tonk Commander").
Let the timer expire at the shooting range (daily: "He Shoots, He Scores!").
Edit: At the Ring Toss the Encounter bar position is right after you missed all of the throws but the next time only 1 of the bars will be shown.

Tomorow I'll check other dailys there

Cheers!
