You're missing a whole coordinate. Check the updated manual.
No idea on crashing. This was supposed to be fixed.
Surely you can see where the confusion is though...
"tileY is floor number (0 to 8). TileX and tileZ can be seen in the editor."
Yet the coordinates we actually see in editor are X and Y (none experimental version)
So how was I supposed to know that A - it wasn't a typo and B - this specific command changes what Y and Z actually mean.
But sure, keep threatening to flex those mod muscles
