Probably another one you guys know about, but there's a fancy looking yacht parked (clipping) through the beach dock.
Spring year 3, Thurs 11th at 5pm. Noticed it when I triggered Wakku's 8 heart event and it was still there after the cutscene.
Platform: PC - Steam
Version: v1.1b-1237
Input: Mouse/Keyboard
Edit: The boat was in the correct position for Yuri's cutscene the next day (Friday).
