Have turned on CI game in our project, and it is applying rules for standard checks (build fail, tests pass/fail), but never getting a score for checkstyle despite changes to warning count.

E.g. output from build like this (even though fixed a checkstyle)
[ci-game] evaluating rule: Build result
[ci-game] scored: 1.0
[ci-game] evaluating rule: Increased number of failed tests
[ci-game] evaluating rule: Increased number of passed tests
[ci-game] evaluating rule: Decreased number of failed tests
[ci-game] evaluating rule: Decreased number of passed tests
[ci-game] evaluating rule: New HIGH priority Findbugs warnings
[ci-game] evaluating rule: New NORMAL priority Findbugs warnings
[ci-game] evaluating rule: New LOW priority Findbugs warnings
[ci-game] evaluating rule: Fixed HIGH priority Findbugs warnings
[ci-game] evaluating rule: Fixed NORMAL priority Findbugs warnings
[ci-game] evaluating rule: Fixed LOW priority Findbugs warnings
[ci-game] evaluating rule: Changed number of checkstyle warnings
No emails were triggered.
Finished: SUCCESS
