same here for me...

coop mode crashes when entering and finishing various levels... hope there is a patch soon to fixe it !!!

Thanks for the reply. Are there more levels that should be avoided?

Same here. Various level even the town. My save is quite the same as above. hope there will be a fix i love shovelknight

Game just crashed to me opening a level... deep noise coming from wiiu... i had to turn it off pressing power button for 3 seconds

I'm doing some research because this crash really worries me... I just found a post on GameFaqs where a guy says he had the same problem and asked Yacht Club Games what to do via mail: "I emailed Yacht Club games and they said it was a bug related to having selected the second chalice before a loading screen"

Let me know if someone can confirm this...
