I was using forge on Narrows (at 3am) when I saw a Mongoose I had not spawned. Then I realized someone was shooting at my flying editor ball. It was someone from my friends list but not sure if anyone else would know to find me. After we played a while he disappeared and I kept going, cleaned up the map and saved. The map now works WITHOUT forge so no one else changes it (I think). BTW: I made a JOUST game using narrows with a sword and hammer at each end. If enough people play, I put shotguns and sticky grenades on deck for shooting at jousters. You basically die every time no matter who hits better or first etc.
