On the screenshot, this is the second massive hole Cocain digged below the Intel, when I descended to fill it again with blocks, was here “building a base” and saying it would stop burying the Intel. But apparently not since he destroyed my blocks anyway.
Earlier in game, surviving a votekick with the same motive.
Buried Intel is super annoying for building since you have to type /kill and that may be slower, and not everyone know this.
