I'd like to request that the new cornerstone "Master Blueprint" Have a progress meter added to the bottom of the tooltip at the bottom, similar to how the tooltip for the Temple's hostility/sacrifice is shown.
Hey there! The cornerstones with a temporary negative consequence (like Master Blueprint) spawn an additional icon on the HUD (with a red outline). To see the progress of the penalty effect, simply hover over it (it tells you how many nodes are left). Once the progress meter reaches 0, the negative effect will disappear from the HUD.
