I’ve encountered this problem a few times now – after speaking with the ghost detha is not building the traps. This issue is resolved by letting her die (which is pretty hard considering there are only oozes nearby and getting them to kill her is hard and takes time). Seriously I can’t believe this bug is still ingame, it has ben for months now.
Also hodgins and tzark bug around quite some times since some patches ago. Instead of actually fixing anything they broke working things.
