Hey there, I am having this problem too now. Thing is that it happens in a warzone where people doesnt even have acces to build. I have replaced signs with air using //replacenear, but it doesnt work out. I am in urgent need of help and if you could come by my server (Legends Of Survival) I would appreciate it alot! I have tried a lot of things, but I cant fix this issue. Thanks in advance. Ps, the server is whitelisted so I might need your ingame name first unless it's "Vultra".
