On 0.19.2 a feature was introduced that make it so the eldritch take over districts as you take over others.
Taking over the park causes the ELD to take over the bar district.
Unless another event stops it, the event for them taking over the bar will happen the morning after you conquered the park.
If Lily’s bar was destroyed and you didn’t have an event where you go save her, you royally fucked up at some point.
To be precise, you didn’t get her to 4 hearts before moving into act 3.
Not getting a character to 4 hearts (at least the ones you’re able to) means that in act 3 they will either go missing or fight against you in the war.
You can figure out where I’m going with that.
