So I was at Dukovs place, and the enclave airdrop triggered. Apparently the vertibird scared the deathclaw and he attacked the reinforcements and wiped the entire squad out.
I've checked FNV edit and the enclave faction is friendly to: DLC03EnclaveBaseDClawFaction "DLC03 Enclave Base Deathclaws" [FACT:0E00946C] but only with TTWFixes.esm, I've checked my load order and confirmed no conflicts through factions (checked several of them) and the faction mentioned above has no relations whatsoever with the enclave itself, just the other enclave deathclaws: DLC03EnclaveDeathclawFaction "DLC03 Enclave Deathclaw Faction" [FACT:0E003895]
I have disabled ALL mods not vanilla TTW and successfully replicated this twice now at the same spot

Edit: yes it was an enclave deathclaw, I forgot it was only FOOK that called them "mind controlled"
Also it seems from the factions only the Adams AFB deathclaws have faction relations to the enclave, and that is only with TTWfixes.esm, however with the ESM normal enclave outpost deathclaws are still attacking all enclave soldiers.
