I saw that the last "random tests broken" issue has been flagged as resolved, though it isn't: the random tests feed already dead "entities" in the algorithm, though they are kept by the tester's algorithm.

e.g: hero: [[3, 4], [2, 0]], opponent: [[1, 2]]
Result from the internal algorithm: hero: [[3, 2], [2, 0]], opponent: []
Possible result from the user, filtering the dead entities afterwars: hero: [[3, 2]], opponent: []

Solution would be to not feed in dead entities
