I think that was specifically targeted against people who wanted some kind of "constant world" MMO mechanic. The ability to deal with intermittent "blips" would be lovely if they could figure it out -- though I suspect that will require a (working) load game feature.
It may have been, it was a while ago after all

But unless this is already in the pipe, it might fall under 'major change and not enough time to implement'. I guess when you're able to reload an autosave before the crash it sort of allows you to get back in the game, but it is cumbersome since everyone needs to quit and start again.
it would be nice to message someone who is IN GAME from the lobby...
Yes, but as far as I know we're still playing with a very bare-bones ICO lobby?
