bad omen potions do not start raids

on realms and servers, when drinking a bad omen potion (I-V) near a villager instead of giving raid omen for 30 seconds before a raid starts, it does nothing except make the noise when it was supposed to 

when u already have the effect bad omen on you before u get within range of a villager the effect just disappears without doing anything

also bad omen V on a personal world does the same thing as bad omen is doing on realms and servers

expected result: gives you bad omen and if ur close to a villager gives raid omen for 30 secs then starts a raid

actual result: does not give raid omen at all

if it does help the realms and servers are using addons specifically ones the owners made themselves
