Load Sudoku: CLICK TO LOADIt is a Sudoku X which I tried to solve as a std sudoku to make it a bit more challenging. I got as long as the sudoku given above. Then I would try the solver, still the standard (not X).

The solution count says 3. But clicking step the solver is coming up with one unique solution. If fires the BUG rule once to get upper left corner solved to 7

Then there is only one solution straight forward

But if you put 1 or 4 in upper left corner there is also one solution

So solution count is correct, and the BUG rule is somewhat too smart. Or at least it only works correct if solution count is 1

In addition the BUG rule find the only solution if you solve it as a x-sudoku

Seems like a simple rule - and I'm sure I coded it. However the solver messes with cages a lot, internally, after all the cage splitting and so on. Been awhile since I looked at this part but I'd have to check. Sounds like I should add a check on client side if it's not there
