 ### Citizens lookclose makes NPC rotate weirdly and not face its crafting station
 
 It has been found that with some options, lookclose can still be used. An example of a working lookclose setup is:
-`/npc lookclose --linkedbody false --disablewhennavigating true --perplayer true --range 3 --targetnpcs false --headonly true --linkedbody false -r false`
+`/npc lookclose --linkedbody false --disablewhennavigating true --perplayer true --range 3 --targetnpcs false --headonly true --linkedbody false`
