Tired of feeling like the only person in the entire Iliac Bay who ever visits shops, temples, and guilds? This mod uses the quest system to occasionally spawn NPCs in buildings you're inside of.

How does it work?

An hour after you enter any city, a few buildings (shops, guilds and temples) will be randomly chosen to be populated with NPCs if you enter them. From there on, every hour you spend inside the city, these NPCs will be despawned, and a new set of buildings will be randomly chosen.
(Timer has been changed to three hours as of version 1.1 to avoid spamming the quest system so much)

There's also an alternate version of the mod which includes taverns among the buildings to spawn NPCs in. The reason why I didn't include taverns in the main version of the mod in the first place is because the NPCs spawned using this method count as "enemies" even if they're not hostile, so if you try to rest in a tavern that's getting populated with NPCs by this mod you will get the "there are enemies nearby" message. I don't consider this a big deal, since all cities in the game have a fuckton of taverns so if you find one you're unable to sleep in you can just go to a different one or wait outside for an hour while the mod resets and chooses a different tavern. You could even attempt to explain this in-character as the tavern having all rooms occupied, or being too noisy for you to be able to sleep. However, I figured most players would probably want to save themselves the annoyance and I removed the taverns from the first upload.

Version 2:
-Added NPC spawns to several types of shops that didn't use to have them
-NPCs from this mod spawning in taverns will no longer prevent you from resting*
*You'll still get the "there are enemies nearby" warning when they first spawn, but once they've finished spawning their presence will not prevent you from going back to sleep
-Due to this, taverns are no longer an optional module (since the reason why I made NPC spawns in taverns a separate download in the first place was the inconvenience of being unable to sleep in a tavern where this mod was spawning NPCs)
-NPCs will only spawn inside shops during daytime.
-Added new dialogue lines based on building type.
-Aside from talking to you, NPCs in taverns have a 1 in 5 chance of doing another action, such as buying you a drink, trying to sell you a trinket, or challenging you to a game. 

Version 1.2 changes:
NPCs will now do random small talk when you click them.
Your legal reputation will be reduced if you attack them, and reduced even further if you kill them

Installation

1. Download the file.
2. Unzip the file inside /StreamingAssets/Questpacks
3. If you're starting a new game, that's all you need to do. If you wanna use the mod on a game you already started, you'll have to open up the console and type startquest PBMASTER to get the mod running.

Special thanks

I wanna thank Jay_H, Hazelnut, and interkarma for putting up with my barrage of dumb questions in the custom quest support thread.
