Dumps
List Alts:
Prat 3.0 (AltNames) : 5 alts found for Edrik: Zatalia-oldblanchy, Valmont-oldblanchy, Chenoeh-oldblanchy, Kumori-oldblanchy, and Elidee-oldblanchy

Find characters:
Prat 3.0 (AltNames) : Found alt: Valmont-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : Found alt: Chenoeh-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : Found alt: Kumori-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : Found alt: Elidee-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : Found alt: Zatalia-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : searched for: Edrik - total matches: 5

Find Characters:
Prat 3.0 (AltNames) : Found alt: Kumori-oldblanchy => main: Edrik
Prat 3.0 (AltNames) : searched for: Kumori - total matches: 1

List Alts:

Dump: value=LibStub("LibAlts-1.0"):GetMain("Kumori")
empty result
Dump: value=LibStub("LibAlts-1.0"):GetAlts("Kumori")
empty result
Dump: value=LibStub("LibAlts-1.0"):GetAlts("Edrik")
[1]="Zatalia-oldblanchy",
[2]="Valmont-oldblanchy",
[3]="Chenoeh-oldblanchy",
[4]="Kumori-oldblanchy",
[5]="Elidee-oldblanchy"
Dump: value=LibStub("LibAlts-1.0"):GetMain("Kumori-oldblanchy")
[1]="Edrik"

I think the cross referencing with LibAlts is breaking with the inconsistent implementation of "char" vs "char-realmName" that classic does.

Version Information (please complete the following information):

• Wow Version: Classic - "1.13.6"
