Implement Spirit Turtle scoring bug

Requires #10 to be implemented first.

As long as Hot Frog is active while a combo made via Hot Frog and Spirit Turtle is active, the combo does not reset - it sometimes even jumps.

As shown in 2:02:

• A x2 combo is made at the right side of the board
• To the left side of the board, the combo is extended, and somehow jumps to Combo x13, then 14
  I'm not sure how the combo jumps from 2 to 13 but at the very least combos should not end.

I'm not sure if this is possible (or plausible) without Spirit Turtle as it is the only way of triggering this bug.

Remember, it's not a bug, it's a feature because someone actually turned it into a strategy
