so I made a giant tank specifically for a hullbreaker and named him hillbreaker so that he didn't despawn and he didn't however until i entered the nether and then he was gone hour wasted and so I'm asking if this is supposed to happen (1.20.1 btw)

all Alex caves hostile mobs disappear (even if they are name tagged) after entering a nether portal

Hi, I know you are not the creator of the mods, but do you know if he still works with mods or has he stopped?

pretty sure hes still working on alex mobs and caves but what do i know
