UPDATED December 28, 2020 to work with latest v.1.69 Patch and to add new buffs and features!
If I ever forget to update the version here at MTS, I always keep the version on my Simularity website up to date, up to the minute along with lots of other mods and cc.

This lot trait will turn any generic lot into a proper graveyard perfect for all of your deceased Sims to move to as their final resting place... if they wish to rest that is! During the day, the graveyard will be populated with mourners paying their respects to lost loved ones. At night, the graveyard will be haunted by those whom have been lost. The lot trait may includes a few more surprises as well. Read on... if you dare!

FEATURES:
Here are the features currently included in this trait mod:

• At 9am to before 10pm: NPC mourners appear to grieve at the graveyard.
• At 10pm to before 5am: NPC ghosts appear to haunt the graveyard.
• Timed emotional buffs will affect your Sim as soon as they step foot in the graveyard and at different times of day/night.
• Your Sim will also receive emotional buffs when they finally leave the graveyard.
• Special buffs for Vampires at different times of day/night though the Vampires Game Pack is not required for this Lot Trait to work. It's just a bonus!

LOT TRAIT BUFFS:
Here are some of the mood buffs you can expect with this trait mod but there are many more:

May They Rest In Peace (Sad +1) - Your Sim is thinking about all the souls whom are buried here including their own relatives and friends whom have past. May they all rest in peace.

Creepy Feeling (Stressed +2) - Being in this graveyard so late at night has given your Sim a creepy, stressed out feeling. Maybe this wasn't the best of ideas? It might be best to come back during the daylight hours, unless they like this sort of thing.

What Am I Doing Out Here?! (Stressed +4) - What am I doing in a graveyard after midnight? Am I crazy?! Did you hear something? I heard something! I need to get out of here!!

Feeling at Peace (Happy +2) - The sadness and loss that your Sim once felt at the graveyard has been replaced with happy memories and feelings of being at peace. They are glad that they visited the graveyard now.

Undead Among the Dead (Sad +1) - Your Vampire Sim is surrounded by the bodies of those who never rose from the grave to become vampires. Your Sim is now pondering whether life as an immortal is truly worth it or if they should have never have become the undead.

In My Element (Energize +2) - It's late at night and your Vampire Sim is surrounded by the dead and the undead. They are truly in their element and ready to go out and stalk their next prey.


CURRENT VERSION:
v1.25 - This the second release of this lot trait. It now includes new buffs for vampires while excluding said vampires from experiencing the same buffs as mortals. Evil Sims will also not experience sadness upon entering the graveyard. If you have suggestions on how it could be further improved, let me know. Thanks!
v.1.25b - Now includes both Spanish and Russian translations! Spanish translation is by CRH and Russian translation is by barbie_hunter.
v.1.25c - Fixed the venue restrictions that should have been there since v1.0. It no longer will work on residential lots as it was intended to be. Sorry for those who were using it on such but it wasn’t supposed to work that way. If I get enough requests to change it back, I may alter it again or create a separate yet similar lot trait for residential lots. Also now includes both German and Portuguese translations! German translation is by granatapfelsaft and Portuguese translation is by Taiyourin.
v.1.26 - Updated for the v.1.69 Sims 4 patch which previously broke this and my other lot traits. Now they work again! YAY!! All other features remain the same. It just works again now.
v.1.3 - Added unique buffs for the following types of Sims: Evil, Squeamish, Gloomy, and Vampires. I also added a weekly visit from the Grim Reaper! All translations are now out of date so if you provided a translation before, I and the community would greatly appreciate it if you would translate the new version. Pretty please?

HOW TO USE:
To use this trait you'll need to go into Build Mode on any given lot. Start by selecting the Venue Type as "Generic" as that seems to be the best choice for a graveyard thus far. Then go to Lot Traits panel and select "Graveyard" which should be this lot trait. See the preview image at the top of this post to see what the lot trait icon and description should look like in the game.

As for the lot itself; build to your heart's content or do a search in the official Sims 4 gallery for #graveyard or #cemetery and I'm sure you'll find something to your liking. The lot trait will work with any type of lot other than residential type lots.

NOTES:
KawaiiStacie (creator of the popular Slice of Life mod) first created a Graveyard Lot Trait mod that was similar to this but has since abandoned that mod and it is no longer available anywhere for download. I created this new lot trait from scratch on my own. I would still like to give props to KawaiiStacie for coming up with the original idea and inspiring me to create my own graveyard lot trait. Thank you.

OVERRIDES:
None

CONFLICTS:
None that I know of.

SPECIAL THANKS:
I created this trait mod using the Mod Constructor v4 by Zerbu. I wish to thank Kutto and Lumpinou from Zerbu's Realm Discord channel for their essential help in creating this lot trait. I also utilized Sims 4 Studio for several edits so thank you to the team behind that program as well. I would like to thank DeathPoke1qa for making the suggestion that I alter the trait to behave differently for vampires and evil Sims which I now have. I may be making more edits in the future because of their suggestions and others. Thank you to MizoreYukii of the Creator Musings Discord channel for helping me figure out the venue restrictions on all my lot traits!
