Since the 1.4 beta, half of my settlements are constantly losing morale/happiness from 80+ down to 40.
My Pip-Boy tells me they lack beds, defenses etc. and are probably one step from rebellion.
This has been a rare and random occurrence previously, only affecting two settlements, but it could always be resolved by visiting the settlement in question and going into workshop mode for a few seconds. The numbers would correct themselves and all would be well in the Commonwealth again. It's a familiar bug, but at least it used to be easily resolved.
No longer.
When I'm on site, it's easy to check that the settlers don't lack for purpose, resources or defenses, they're just miserable anyway. I've taken to leading each of these supposedly grown advlts to bed to make sure the bed count and the number of actually rested settlers add up. This sometimes boosts morale by 6-10 points, but they are lost as soon as I leave.
When I return, those beds are unassigned.
While it would seem likely that this depression epidemic is responsible for many of my supply lines failing, this isn't really the case. The provisioners turn up where they should, they simply don't connect the workshops. Maybe they're performing some work-to-rule strike action.
Tired jokes aside, my settlements are shot to hell on three characters and this coincides perfectly with the 1.4 update. The game is pretty much unplayable since it no longer adheres to its own rules.
I don't know what to do, I've had it and I'm going to bed.
