Done Pseudo inversion ritual not working

Did setup a pseudo inversion sigil ritual in the end... everything like it should be done... when shift right clicking on the beacon it said, everything is correct, sacrifice someone who would sacrifice himself... did spawn an iron golem on top, killed him, but nothing happened... ritual is not working... tried the same setup in single player. worked there

 

what u kill him with?

 

First try a Tinkers Cleaver, then a Vanilla Diamond Sword...

 

@Junior Administrator @Administrator please assist

 

did you do a normal iron golem with 4 blocks of iron and a pumpkin or did you use a spawn egg?

 

did you kill him using a tinkers sword of any kind?

 

Found the problem... the golem that spawns is from Utility Mobs... how can i spawn a normal one?
