Is it a bug that stacks lock down in Single-Card even if they have additional groups below the 7-to-1 at its top? It's basically a softlock when it happens (forcing Undo, that is) and feels like it adds nothing but frustration to finishing up a solve that by all rights should have been won. Or is this a skill issue?
This was changed because it felt to me that it was a bit too easy to interrupt the slot-locking by just placing a 2-1-2 stack at the end of a 7-6-5-4-3 pile. I do agree that it adds to the frustration and isn't *that* difficult to work around, but I think it's still a slight improvement over the previous implementation.
