Server patch \#34 introduced a server-crashing bug where you could crash a Scissors 1.17.1 server simply by going near the world border.This commit removes that original patch and re-implements part of what the patch set out to do separately so that the painting crash exploit doesn't work, but the server won't crash when you try to go near the world border.
