Anytime I post a comment (in a non local community?) it doesn't show up. It's there I just can't see it unless I go to my own profile or someone replies to it.
DLC is now available on all platforms including Pico, as is passthrough mode. Cross-platform multiplayer is currently in beta and should be coming soon to all platforms as well.
Also I just edited "lost" to "post" but I'm not seeing that change either. Maybe it saved, maybe it didn't..
