hiya subatomic! I think i answered this on discord, but so others who read this know the answer to this question i'll answer here too.
You always place the quest token out on the right tile. In this case it wants a very specific event tile. If it's not in your world deck (the stack of tiles you draw from) or the general terrain pile (the stack that hasn't been included in the world deck yet) then that event is somewhere on your map, so instead of flipping all the grassland tiles you have making your map a mess, i jus thought, no need to remember, just use a blank grassland tile. In your case, you happen to know which tile is Grassland R2 cause the badge was placed there. You should place the quest token on that same tile. (i'll see if i can rework some wording on that in the hex kit to make it more clear) there's an odd balance when writing for intention and clarity and often (like this whole paragraph lol) it takes too many words to explain all possible situations. sorry for any confusion! thank you for asking questions! happy to answer them!
