Not just me. Henry and a few more people had this problem too.
I got these tents from quests. Didn't craft. I used these tents by the other character successfully (he's rerolled now).
So tents don't work sometimes. No idea what it depend on. Not on the ranger perk for sure, cuz I used them with it and the character on the screens has it too. I tried to put them anywhere on wm with this character. Please, don't suggest doing it with another character. Just fix the bug and tell us when it's fixed.
I also would love to know what caused it.
