Try to put 2 fastest squads on the top tent, 2 in middle and 1 on the last one. I put 2 of my fastest squads in the middle and it worked for me on the first try, but after that I found out it better if you put the fastest squad on the top ( and pray for RNG of course ). I keep farming ?-4 for Life Crystals and it work for me every single time, yup every SINGLE time.
