Mob Spawners not working

[matdemon2000]

Hi recently ive been working a lot on mob spawners and suddenly one day I get on the mobs don't get hostile and so it makes my spawner useless and the other day it was working fine so I need to know if this issue will be fixed or if it was put in for a reason

an answer would be nice

mobs don't get hostile

Correct, mobs generated from a spawner no longer become hostile.

makes my spawner useless

Nope, plenty of ways to make it work

Actually they spawn, but my problem is they're so friendly even the zombies dont attack me but tnx to that i can kill them easily
