Changes and fixes:

Widow's wine:

• It is now split into two activations, major and minor; the minor one activates first and has a 3-second cooldown, while the major one activates independently of the cooldown but only triggers at critical health.
• Now it freezes zombies on all maps instead of just changing their movement state.
• More points earned for immobilized enemies 10 -> 20 per tick

Burn Heart:

• Now it "dries" the mud in Origins and allows you to move at normal speed.

Dying Wish:

• It now works correctly on all maps.
• The cooldown now increases by 2 minutes with each use, up to a maximum of 15 minutes.

Executioner's Edge:

• Now it kills on all maps, with the sole exception of Tranzit in Standard mode.
• Executioner's Edge: increased the point bonus 50 → 150. (I realize it was to low for the price)

Perk machines:

• Now it displays the perk machines in English, whereas they were previously in Spanish. (Sorry I didn't notice)
