So after you both write your introduction posts which are rightfully going to have a lot to establish, you get down to the actual interactions and everything grinds to a halt. Posts become slower. Your partner is writing a lot per post, but there's not much you can actually reply to, so you focus mainly on your character's emotions, how their reactions relate to their backstory, etc etc. That is, until, one of you is burned out by the slow pace of the plot and the project dies before clearing a single page.

this is not an advanced specific issue and i have encountered it the most in casual (though casual is basically advanced-lite now with all this high-casual bullshit)
