Hello,
I was able to watch your recording a few days ago, and it does seem quite unusual that your sniper ammo was locked. That said, this appears to be the first reported case of this issue, as I couldn’t find any similar bug mentioned on the forums.
Unfortunately, the link you shared is no longer working. I also noticed that you mentioned being away for the time being. When you have a moment, could you please confirm whether the issue disappeared afterward or if it continued to occur permanently after the first time it happened?
