civbreak doesnt work

[12A1_07_Farrel Christian Ardan]

i try to use civbreak on b77 and 1.8.9 on an annihlation server and it fails it just kinda make the block disappear. then i test it out on my own server with annihlation plugins in it and try the civbreak turns out it still just make the block disappear. any solution or something?
BTW i didnt install any anti cheat plugins on my server, but at the annihlation server theres prolly an anti cheat like matrix or something
