PoM puppets respawn time

[scifo76]

The puppets were up when me and a friend came to the camp.
Killed the first Tribunal Puppet and while fighting the 2nd Tribunal Puppet, the first one respawned on top of us. This was MAX 10 minutes after we had killed the first puppet.
Is this normal? What is their respawn time? Looking at some videos from this camp, it should be possible to clear the whole puppet area before anything respawns.
What am I missing? Has there been a new patch changing things? [You must be logged in to view images. Log in or Register.]
