Now I know why... I questioned 2mi127 about Outertale AU three days ago (and she replied one day after) and here's their response:
Me : Ummm... Excuse me are you still into Undertale? And do you still remember your AU Outertale?
2mi127: Uhh yeah I'm not into Undertale anymore, sorry ><
What does this mean everybody!? 😨😰😫😵
