So I just noticed that a single Vanilla installation (looks like a medical or research facility) is spawning near my FOB. I double checked all modules, including all Custom Obj modules for both BLUFOR and OPFOR and Create HQ is set to NO on all of them. I have no random camps set either. It seems to be spawning in the same spot everytime but there is no module over that area in the editor.
Is it a bug or is there something I'm missing?
