Fish entity won't replace to a zombie

[feral crater]

This does not work for some reason

Skript reloads fine but when I fish I get the normal items

[safe coyote]

debug

it’s most likely you cant set the entity of a fishing rod to a zombie

you gotta spawn a zombie at location of fishing hook

if you are trying to make it like skyblock, propel the zombie towards the player using a vector at velocity 1.5 or something

good luck
