WowAce

Update: When I disabled 'Reverse bar growth', none of these errors were thrown anymore. For now that seems like the only workaround.

I just reinstalled WoW after a year or so. I grabbed the newest version of Skada and set it up how I like it. After changing a setting (I can't remember which), the meters no longer reset on their own and the reset button doesn't work.

I've got 5 errors/stack traces for you. The first three are thrown when I first login or reload my UI; the second of which is thrown once for each meter type (damage, healing, etc). The last two occur when I press the reset button and exit combat.

On login/reload:

This one is thrown once for every meter type whenever I login/reload. I'll only post the first, but the rest of them differ only in that the module is Healing/Overhealing/DamageTaken/etc:

Experiencing identical issue, only occurring when "Reverse bar growth" is enabled. Persisted through Skada reinstall, user settings purge, reloads of UI and WoW restarts.

Tested disabling all addons except Skada and the issue was no longer present. However, when re-enabling all previously disabled addons the issue did not initially return as expected while solo. After joining a party however, the issue returned as before.
