The lazy bastards! 
The moment a mod or mods are involved then you would need to remove those to test if it happens in the core game - otherwise pop a query in the respective Modders Discord (they all have one).
You have more than one Thrall-affecting mod installed. Add the Purge and Bar mechanics and you have a lot of potential for confusion. Good luck. But check with the Modders Discords first. FC cannot/won’t/shouldn’t be expected to address any issues the moment mods are in the mix.
