So after some quick research I found out they blocked it 'cause they considered it a bug (or something on the lines of that) which ok I get it. Plus you can technically you can use 0 tick farms to crash servers which well isn't ideal for people who host big servers, but as a person who only plays with his friends every and a closed server we NEED 0 tick farms to progress in the game. Like MANY other people suggested I think they should make it an option to turn on/off the 0 tick farms.
