Changes

The amount of levels in a mine is fixed and depends on the location of the mining facility:

In each level, the amount of '''mineshafts''' that can be found is equal to '''4+level number''' (e.g. Level 6 will have 4+6 = 10 mineshafts). Mineshafts are numbered using '''letters''' (e.g. shaft A, B, C, D...). Each mineshaft is '''3d10 sections''' long, and sections are numbered using '''numerals''' (section 1, 2, 3...).
