update : Finished "trouble in the den" chat choose "remain calm" action, but still no third heart.
thats not what gives you the heart, you go home AFTER you choose the remain calm and it also is nighttime. you should then get a new event which is Logan asking you to go with him out because he wants to handle some stuff. the end of this is where you get the third heart.
(Also thank you for doing some stuff as I was completely stuck as to why you weren't getting the chat option, sorry I couldn't help more on that.)
np, and it may take a minute as well so thank you for saying I can take my time, if you wanna you can also check out a guy named Ben Dover's guide and see if he has something for this event I'm missing that you need. it could find that thing I'm missing.
