Willy dissapearing (bug)

So its spring 20 and I think Willy has been missing for like 3 days now, I can go into his store and everything and he just wont be behind the counter or anywhere else. I don't have any mods installed and haven't messed with the game files so I don't know where to go from here, anything I can do to get him back I miss him :(

​

Edit: He was in front of Leahs house! Thanks for the help guys
