So I was in the tunnel in bm_c2a4h, leading to bm_c2a5h, and as my game loads bm_c2a5h I decided I wanted to go back to bm_c2a4h and explore the tunnel a bit more. When bm_c2a4h loaded back up, the only weapon showing up in the weapons menu was my crowbar (not even my currently equipped crossbow was appearing.) Going back to bm_c2a5h does not bring the weapons back either. The only option is to reload from my last save where I did have weapons.
Seemed like a pretty troublesome bug, so I thought it’d be best to report it immediately.
