I'm not entirely sure what's going on, so I apologize if whatever this bug is has already been reported. That said...
When I load up my save in the Refugee Center, one of the NPCs attempts to reload their Mosin-Nagant with a 7.62x54mmR clip. An error message pops stating that it failed, the weapon can't be reloaded with that. Then it tries to reload it again. Keeps doing that until the game detects the infinite loop and turns on debug mode. Here's the save and debug.log:
Reload Bug.zip
Load the save, dismiss all the errors about #41821 and about something not fitting in a holster, then take one step.
The gun reloads or the character doesn't try to reload a gun that's not supposed to reload that way. And no errors, that too.
The bug is caused by Mosin Nagants, along with many other guns, currently being broken. This issue has been reported several times over the past week or so. Nobody's come up with any solution yet, at least that I know of, so don't expect this to be resolved any time soon.
No worries. Just glad to know it's on the radar, even if there's no solution yet.
and again, since i am tracking series with mosin nagants
maybe related #42161
