For some reason, when there is very specifically a "Concrete" blueprint present on the map (the concrete floor blueprint), I can't place a cave entrance, and the blueprint visual that follows the mouse cursor before placing it is invisible (ONLY when it can be placed. When something is in the way, like a wall or another object, the red blueprint indicating it can't be placed is visible).

To be clear, I am running many mods, and one of them (Industrial concrete) does change the recipe of the concrete floor. Maybe that's the issue?

Below are the error logs. "Ref 9C746EE3" happens when I click to place the blueprint and "Ref 904AF101" happens once per tick while my cursor is hovering over a placeable spot:
