Well nice one all you shining wits, you whine about no events and then whine when there is one cos it's not what you wanted. Due to my personal activities, I never actually ran any BK before they pulled it anyway, so I can't comment on rewards. I can say that yes, the monochrome made things different and harder to see but I managed to find collectibles on my island even so.
And if you really really hated it, and couldn't stand to look at that mono picture for more than 5 minutes, well, the whole event was only 2 days fer chrissakes, you could've just manned up and done minimal maintenance for those 2 days and waited for it to finish instead of getting it pulled before some people even had a chance to SEE it.
If it wasn't perfect, like some things didn't get included, well, life ain't perfect. If you go around expecting perfection in everything then you're gonna be constantly disappointed, which is a poor way to live. Me, I was looking forward to a couple days R'n'R from running VLTs and rebuilding troops flat out. But I didn't get that, so thanks a bunch.
