did you get any besides belt acheivements recently?
"i made a mod" is not working for sure, same goes for cassius clay, glass joe, hittin air, die by the sword etc.
i heard recently that those related to "win X fights in said mod" don't work either, graduating tests are not done anymore so those are out aswell, a big part of the achievements were related to some events and cannot be achieved in any other way.
