I am in the process of taking over a Navezgane Corrections, and at one point while I was transferring stuff from my starter base to there, I came back to NC to find that some of the sleepers had respawned, despite putting down enough Land Claim Blocks to fully cover the area without gaps. Discussion on Steam led me to believe the most likely cause to be a failure to clear the place totally on the first pass. I think I've managed it, but only time will tell.
My suggestion therefore is, much like when doing a clear quest, have the POI indicate when all sleepers have been killed, perhaps by having the skulls under the title turn green?
