Changes

Insanity path tiles are usually found inside mines, on any tile more than 2 tiles inside minesaway from any ore veins or cave exits. The tiles Note that reinforcements and rock salt do not necessarily have to be flatcount as "ore" and will not block Insanity tiles from appearing.

You should be able to create your own insanity path tile by flattening tiles in a mine, then testing them. After completing a meditation on a path of insanity tile the usual message of "This is indeed a special place" will not appear. Due to this you may need to try moving to different tiles and repeatedly meditating until you get a path question in order to advance. Certain Path of Insanity-specific "trance" messages may also appear when beginning to meditate, making it clearer that the tile is special.
