The problem with the tamable papoo spawn south of Crystal Center seems to have been corrected. Yesterday I went to Next Island and found Adaptable Brown Papoos that can be tamed. These are level 1 creatures and are therefore very easy to tame. Once tamed, their name is changed and they are called Lofven Papoos. They cannot be exported to any other planet so you can only summon them on Next Island and Secret Island for the time being.
Edit: The issue is not solved. Most spawning papoos are immediately killed by the nearby turret. It is only in exceptional situations that some of them spawn outside of the turret range and can survive.
