But when I return to talk to the barge guy to get back to cottonwood, my weapons dont automatically get returned like with casinos.
I check the 3 weapons containers at the entrance of the Fort and they are empty. 
Can any of you guys tell me what's the container (and where) that contain my stripped weapons? I figure this is a rare bug since there's only one google search result of this bug from a long time ago on console.
EDIT: It's rare alright~ Because it's not consistent. A few reload later on it work normally. possibly just a hickup, which is not rare around FNV engine.
To save trouble, I just drop hot tnt onto the pants of gate guards and the barge guy~ Spare me the process of stripping~
