hello first of all I congratulate you for the great performance in creating the game!!!!

I think it's a bug that I can't get into Simeon's house after spring starts, says it's closed

And i culdn´t find Kiera. I dont know if you have not yet added to the game

Thanks for all!!. And sorry  for my grammar I don't speak much English

I second both of these, Kiera is Sven the blacksmith's wife right? Where she at doe

Kiera hasn't been implemented in the game yet. In the discord server there's a roadmap which shows the future features and content to be added. I found her name on that to add list, so for now I can't do that lockbox quiz.

Hello, I think Yazura already took care of this but yes Kiera is not in the game yet. I believe I’m going to put a warning on any quest mentioning her to tell the player she doesn’t exist yet.

Aside from that Simeon’s house is locked unless he is inside it. As is the case for everyone. Simeon is in his house usually from around 11:00 AM to 5:30 PM I believe. If you can’t get in ever it’s a bug I’d be happy to look into but I haven’t heard of anyone saying that yet.
