The Meaning of Life, the Universe, and Everything.
I discovered the hard way (don't ask, I might get profane) that the first 4 arguments in a command are no longer assumed to be x,y,z,r. Have there been any other changes (between 1.10.2 and 1.11.2) that might affect how my existing command blocks work? I have used blockdata, clear, clone, entitydata, fill, gamemode, give, kill, say, setblock, spawnpoint, summon, testfor, testforblock(s) and tp, many with tilde notation where allowed. TIA for your help.
