“Free for all, all for me” achievement is bugged, no mount

I have recently unlocked the achievement but didn’t receive mount. I’m assuming it’s due to the warband update. I’ve seen many other people post about this issue in the forums (since August) and there still doesn’t seem to be a fix for this

I also have this problem. I earned the achievement in 2018 but never got the mount. Didn’t notice until now.
