I'll have to do some more testing to find the culprit, but I've been noticing that since a few other of my mods updated, bone weaponry just disappears when a pawn gets downed. Once I find out what's doing it, I'll post!

You could try placing B&B further down the load order, that might resolve it. No guarantees though. Are you using more mods interacting with bonded weapons or pawn equipment logic?

Nothing that messes with bonded weaponry. I am using the "Simple Sidearms" mod, but it hasn't been updated in the last few days, which is the time period in which my bone weaponry suddenly started to disappear.

I'm unsure if any of these are not compatible, but I was running them among many others when my weapon raised way to high in damage. These are the most likely offenders I can think of.
