Done Me Assembly chamber wont work

I built an Assembly chamber following all the rules i even went into singleplayer and built the same structure block for block but for some reason on the server the Assembly chamber wont change appearance and work. did they get disabled at some point due to performance?

 

you probs cant build it large due to lagg

 

its only a 5x5x5
i had one before but wanted to go to 7x7x7 but it didnt work so i built my original 5x5x5 which with 100% cetainty was working before i re-built it

 

well, so just do with 5x5x5... i think is bcz of lag u can't do more than 5x5x5
^^
