Undo button bricks the game

[StoneyEagle]

When using the undo button the game becomes impossible to finish. Some cards become stuck and others will no longer move to an empty spot on the table. Cards that are not stacked become tied to one another and move when picking up a stack.

Here is an example of a tied card when picking up 3,2 and A from the last 8 on the table

It also does not allow me to move kings to an empty spot on the table.
