crockpot theory here: the 1.6 update for the switch took awhile to roll out. maybe this bug is a bug, but it could be a "sorry this took so long" feature. it hardly seems like an exploit because that implies there's a legit way to build up friendship, which there IS, but it's inaccessible to switch players right now. i dont see why this is becoming a federal issue for some people because it's not game breaking in the slightest. sure, its not working as intended, but the game still runs fine. ive started a completely new save since the update and this is the only bug ive found at all.
yall need to relax with the complaining and instant aggro regarding patches and updates. this isnt a big studio working on the game and theyve got lives and plans beyond it.
