I am creating a new thread because I cannon bump my original one due to no response.
Regarding this known issue, the voiceline for hero loadouts using an altered VO resets after every game. It does not simply happen when changing between skins, it happens every time and after every game.
The bullet point in the known issues for the voice line issue is thus not accurate:
Continuing the discussion from Known Issues List:
It should read:
*After setting a loadout with a skin that uses altered or replaced VO, the voiceline will reset after every game played or when selecting another skin.
