And can someone explain what happened for him to delete his tileset and ask to be banned?
Their mood happened.
You can obtain the tileset by either downloading an old version of Cataclysm-DDA like 0.D or the source code of that which both still contain it and copy the folder over - but it will miss all new monsters - or find his/her github account (which I’m hesitant to link here as I do not support his/her way of behaving and linking it might lead some to falsely see it as validation) and download it from there.
Hello, i found his github account and downloaded there. Thanks a lot.
