The rules say that the boxes are destroyed before the movement is done.
However, if there is a box at say (10, 5) and it is about to be destroyed, and I am issuing the command “MOVE 10 5” in the same turn, the game does not allow me to make that move.
I seems that there is a few issues and i believe some people have likely integrated those behaviors in their algorithm thinking “oh well that’s how it works”.
If they fix the contest now, some people might find out later on that their code didn’t work properly anymore and feel that it’s unfair as it’s not obvious to guess that behaviors would change during the contest actually…
If CG decide to fix these bug they are better off at least sending some email so people are aware of modifications.
I think of people like Romka who don’t seem to have much time for contest and might just get screwed with somewhat unexpected changes.
