A few days ago, while enjoying an evening meal, the thought came into my head of "What would happen if you block all of the invisible spawn points on Forge World?" Well, the next day, me, The Mighty Dino, and SlingingCaleb repeatedly killed ourselves and blocked the places we respawned with large blocks. When all of them were blocked, any further deaths resulted in a black screen, from which you could still access the start menu, but nothing else. I have this totally pointless map on my fileshare. Anyway, I'm just sharing. <3
A similar glitch happens when using a glitched Infection variant with Teams enabled. The game prevents you from spawning (actually, your corpses just appear at every spawn point, one per tenth of a second) and you fade to blackscreen. The weird thing is that you can't even switch the camera to another player while you're waiting to respawn.
Hm, nice. Never thought of doing that because I never really cared; but hey, everything has to get discovered someday, right?
I posted because I suspect they're the same glitch: if you can't spawn, you go to blackscreen. In any case, nice find. :3
