I experienced a random, large explosion at my base that seems to have taken place in the room where I was storing my power generators. There was one random person in my server that I suspect may be behind this but I didn't see anything. The problem is that afterwards, I am unable to replace any of the blocks that are now missing. I also can't place anything like turrets or electric relays on the walls that are still standing. See video for reference. Is there a way to fix this? Or maybe even to reload my previous save from before the explosion? Any help appreciated, thank you!
