I had this happen to me earlier today after the first real time i decided to make a nice camp. Spent 2hrs on the planning & design, was gone the very next login.

Now I have a simplified blueprint of several foundations with every crafting bench, a stash box, bed, instrument & other such necessities which is appropriately titled "FUCK CAMPS".

I don't plan on building an actual camp again until Bethesda fixes this bullshit, the worse part is the camp that overwrite mine didn't overlap mine physically, it was on the exact opposite side of the pond. It could've been a cool "hey neighbor" moment, but instead I considered sending a mini-nuke & a couple rockets into his window even though it wasn't his fault. I didn't of course & just logged off for the night.
