I'm stuck to this task what I do?where should I go to trigger this event?
Either you need to be patient until Sparks visits you in the morning or you chose to not have Sparks wake you up in the mornings altogether.
If it's the latter, download this and put it in your \A Better Place\game folder. I made a mistake when doing a quick fix for something else.
I can't test it though, because the entire nighttime visit system is being recoded in the rewrite, but theoretically it should work.
If you're on mobile... I may have to upload a fixed version for you.
Okay... So you are on mobile. That makes things harder.
Here, I uploaded a whole new .apk with the fix. Try that.
Note, this fix also makes it so Sparks won't visit in the mornings unless there's an event, but that doesn't matter for this version (and she wasn't visiting in the first place).
