is the update not working for anyone else? i keep checking up on it periodically, but there's never any new content. it's probably just a problem with my computer or something like that, but i thought i'd at least ask.
Could it be you used a save from chapter 4? It said in the update to use saves earlier than that or they'd be broken. If not, then I don't know, sorry. I replayed the whole game from the start so for me it worked just fine.
