||I think it was a pretty good problem for the finals.
Although I tested the problem off-site, after 3 hours I had a very good solution and spend the next 2-3 hours tweaking things and trying slightly different settings. So, I think 12 hours is enough for a final, after 10-12 hours its difficult to think straight. I'm not an expert with algorithms matches, and I could came up with a solution that had a great chance of winning (In only 6 hours), so I won't classify this problem as an algorithm match, it felt very marathon like.
I can understand the amount of zero scores. There is a lot of possible cases where you would try to built a base in the same move on the same spot by different workers, or move a worker where another worker will be building, or even trying to move where another worker is collection resources, spawning a worker where another worker wants to move, etc.
