its not an Option there
What does the quest say?
If it says "I should gather everyone at Kora's treehouse when I'm ready to go home.", then the option to "go home" is at the treehouse in the morning and afternoon.
If it's not, then I don't know what could be wrong because one cannot be true and not the other.
You can join the discord or DM me there and I can look at your save if needed.
If you're on v0.12.0 then the next version won't fix it because nothing with that part is changed.
As I said,
- the quest saying to go to the treehouse and
- the option to go home being gone
can not both be true, because they both depend on the same variable.
If you want further help, I'm available on Discord.
