pretty sure it happens because the last column doesnt finish its animation when the clock finishes. Also, would love some way to know or influence future columns, ive gotten 5 1s in a row in num6 multiple times.
New bug (probably from fixing the old one): when you push down a column, it keeps flashing. (just a visual thing, you cant push it multiple times at once.)
Also, I would suggest a bag system for the columns (Say, a column can only get pushed down 3 times in total before every other one is), to fix getting unlucky, but any solution is good
