I just encountered a bug eith rhinos 🦏. If you are taming any dino and taming progress is almost done like 70% or 80% and if their torpor is full enough for rest than you can leave your dino there and fly straight to your home or sny far you want(and request him at any place from tames option). And it is also the safest way to save your tame from another wild dinos.. if you are not in that area no dinos gonna spawn.. for example if you are not in ice biom than ice biom does not exist. It will be generate by computer only if player is in range. So no dino spawn and you are safe.... But this just dont work in rhinos. If you leave them they just awake when you comes again.
Ez tame even for early game , just use 4 billboards, put around rhino when still unaggro and then when the rhino is trapped with the billaboards just start shooting tranqs . ( Can use wooden billaboards)
