First 2 weight events added to remaining NPCs (+new bug)

Hello! The remaining NPCs that didn't have their first 2 weight events now have them!

This update was also going to add Reco's and Valentine's Mom's 4 weight events, but due to a newly discovered bug, I have decided to add them with the update that fixes that (probably by Sunday)! This bug mainly affects people with less than 16 GB of RAM. 

edit: F5 key doesn't seem to consistently refresh the game's Memory usage, better to close and open the game

New bugs:

1. Throughout a play session, each time the background image changes, the game will take up more computer Memory (this worsens if you change backgrounds quickly by opening and closing the shop multiple times , for example) 

[temporary fix  for if your computer has less than 16GB of Memory , you can check how much you have by opening Task Manager and going to the 'Performance' tab:  Save often and then close and restart your game session]

2. Upon loading, sometimes the incorrect background image will be shown
