Okay, I don't know if it's the way I speak or the way my accent sounds, but lately I've been having trouble calling villagers. I was trying to call "Filbert," but the way the game interprets it gets confused. One minute it thinks I was calling on "Admiral," and the next it thinks I called "Kapp'n." I looked all over my island for Filbert. I checked all the villager homes to see if he was there. He wasn't. Checked the shops (Nook Cranny and Able Sisters). He wasn't there. Then I tried the Mesusum. He wasn't there.
I must sound like a manic, shouting Filbert's name 9 or 10 times, and the game is not really helping my situation. I eventually found him at the bottom-right corner of the island, which is the beach. I was like, "Are you serious right now?!"
Maybe I'm going crazy, but this megaphone is so frustrating to use.
