Wrong solo scenarios
I am playing through our old box of Gloomhaven 1st ed. We just recently unlocked envelope X and I usually use a retailer in my country that is a small, online store for games. I went to their website and checked if they had the X-reward, as I have seen it previously and I saw while scrolling their Gloomhaven content that they had the Solo scenarios back in stock, and I have been after them for a while! So I bought them too. But after opening to play the music note scenario I realised that these are clearly updated for 2nd edition and there are mechanics in these scenarios that I know nothing about. Is there any easy fix to this, like maybe a pdf or something to see differences (I couldn’t find anything after a quick search online) or am I just going to have to try to return these?
