I randomly checked out this mod and noticed that you have a license issue on your hand, since you accepted a contribution from a German collaborator.

German copyright law is incompatible with the Unlicense, since a dedication of a work into the public domain (or the parallel legal concept of "Gemeinfreiheit") is usually argued to be impossible under the law due article 29 of the act expressively prohibiting the transfer of the copyright.

I believe that puts the commits 373015e, 483d389 and f554205 in violation of your license, because the author can not legally comply with it's core requirement.

This mod is no longer necessary as of 1.20 as Mojang fixed the issue themselves. See #24
