The 0 0 of my world is ocean more than 20 blocks from the shore and always has 5-10 foxes in a huddle when I come by.
Code analysis (1.18.1 yarn mapping): (credit to Harley Speedthrust on YouTube and Aria on Fabricord, see the original analysis on YouTube comment)
FoxEntity$AvoidDaylightGoal extends EscapeSunlightGoa. EscapeSunlightGoa defines three doubles for the target X/Y/Z coordinates, and is initialized to 0 by default. This is set by EscapeSunlightGoal#targetShadedPos. However, this method will not be called if it is thundering; AvoidDaylightGoal#canStart L1017 early-returns true if it is thundering, skipping the method call at the end of canStart method. Since the target position is never set, it will always be 0, 0, 0.
