Just jumped in after wow 18+ gb patch.
Would be nice if on map which safehouses have the storage let you know. So your not wasteing time FT to a safehouse just to realize it doesnt have storage box.
Or put them in all safehouses.
As far as I know, all safehouses have storage boxes. If you’ve found one without, feel free to post it in Bug Reports so it can be fixed 
I haven’t had a chance to test the update but patch notes say “Most Safehouses now come equipped with the brand new “Plundra” Storage Box” not all
The recently accessible safehouse north-east of Broskulla has not, it seems to me.
Some storages are tucked in hard to see. Kinda like how the bike 
station is hiding in at some safe houses. Like @Zesiir said, if it’s not there give them devs a heads up.
any safehouse that is a structure should have the plundra, camp sites etc do not, as a general trend
There doesn’t seem to be one at Vassalan Bunker as far as I can see, even after having switched power off/on again. Though its a huge place so I may have missed it.
