I goggled, but it was from 0.6 version of the game and it was from Reddit. So to start...
After grinding 19 hours to get sandbox mode, I figured let's relax in Ambience mode, you know just to get some sort of breather. After playing for a while in that gamemode... I decided to ask
How safe is the ambience mode? It said there's no random night event or signal... And all you do is just scan and get profit. Something like that (I'm outside of gaming area while writing this)
However, what happened was that in the radar there was an additional dot, I haven't placed any cameras, or order something, it was day 2. By day 3 around 0100 hour, I can't save spam (yes I'm a coward) I looked around the base and found nothing.
So, is ambience mode actually safe? Safe from entity, Safe from signals, safe from becoming a Lego character by the Yellow wisp?
