Return of Reckoning

Hello,

I reveiced that message after a solo kill at 240AAO:
I had a message : "you somehow gained an amount of renown larger than the system allows (17500). This gain has been prevented. "

and I didn't get any renown for it. Would you know why ? How does it work on that case?

this kill : https://killboard.returnofreckoning.com/kill/14531631

Thanks
