Hey,

I was wondering if taking the iron from a buried treasure would make the run invalid.

Note: no map or any structure is used just the chest

is into the game, completly allowed well, if the chess cant appear with structures activated, then is for the structures category, but not sure about that chess even if it can appear without structures, it could be discussed if you do a set seed of that seed with activated structures to get the good seed beside that, ye
