Foundations keep breaking - Hacker Valley

I’m trying to build a small base in hacker valley, everytime I go to place a foundation it breaks… any ideas?

Server is vanilla.

Happened on my server earlier too, had to restart it to fix.

Same, reboot seems to fix it. But it is rather annoying.

I was just on the US central 5 server and this keeps happening to me. Every foundation from one side of the map to the other, breaks as soon as I drop it.
