Went mining with a concussion and the Quarryartz I was mining out was higher than my current masonry. My masonry was 190 and the quarryartz was coming out as q202.
As far as I understand, your masonry hardcaps stones you mine and your tool softcaps them. Therefore I don't understand how I was getting q202 quarryartz concussed, unless the game was ignoring my concussion's penalty.
My stats with no concussion make my masonry 205.
