The weirdest thing happened tonight, while playing Starbound. I was playing offline on a planet I made with the Transponder Mod and a snow Terraformer. In the middle of building a large settlement there, the air went red and S.A.I.L announced that a destructive force was heading my way, and to prepare for a fight and large tile destruction. Then, a red skull time icon with a helmet appeared below my healthbar, and the tooltip read "Your Doom is approaching.." This was my first time ever seeing it, and it was too vague to know what to expect. No one seemed to discuss it. I panicked at the thought of my hard work being destroyed, and bolted back to my ship, without even thinking to get a snapshot. I came back, and everything was still fine. Does anyone know what this is?
