While inside the crystal cave on Dantooine, I swapped party members to equip my personal crystal. Afterwards I tried to leave and the Kinrath hatchlings respawned when walking a short distance from the crystal formations. I tested this over and over by changing party members and it seems to continue to do so as long as you swap members inside the crystal area. I have not left the cave yet to see if you can return and use the glitch. Just thought I would share this with everyone. If someone could test returning to the cave and changing party members. Would be a great help.
