Troop perk inoperative

I have an uber cape that should give extra defense & attack for my cannons.

the issue is whether I wear it or not, it just doesn’t change my cannon stats!

any idea as to why ?!!!

thanks.

Changes can be seen when you go to change the troops or spells before a battle (using the matchmaker). Changes of perks worn can’t be seen in the troops academy or wizard’s tower directly. Hope it helps. =)

Yeah, thanks, finally got it!!!
