Bug with Drill Sergeant Skunk buff
Yesterday I my barracks production time was telling me I had 1.7 days worth of troops queued with about 3 hours of a Drill Sergeant remaining only for it to drop to 10 hours when a new buff was applied on the old one expiring. Today I've just run out the final couple of hours of a Drill Sergeant buff where the barracks was reporting 15 hours of production remaining and it's now reporting 11 hours 45 minutes remaining without having applied a new buff. It seems the effect of the buff is being lost at least three hours before it expires, possibly more.
I logged out and even closed the browser a couple of times on both occasions, but it had effect on the problem.
