there's a known glitch wherein the x2 icon stops displaying when your clan reaches 20,000 points collectively rather than tracking it for each individual member. plarium is aware of it and swears that they're working on a solution.

the three objectives with x2 this CvC are ice golem, arena, and gear.

2x cvc points on ice golem, arena, and gear upgrading
