Was fighting Bassus and the Hardlight Ammo Crate in the room wouldn’t refill. It kept saying my ammo was full when it wasn’t. I was using the Sentinel Beam. I’m not entirely sure if it happens with other crates or just the Sentinel Beam but I remember it happening a few times in my 1st playthrough. This also hasn’t happen with Kinetic, Plasma, Shock, or Power Ammo crates, so idk what’s up with Hardlight.
Has anyone else noticed this?
Hardlight ammo crates only work for Sentinel Beam, Heatwave, and Cindershot I believe.
Also important to note that they will not refill your ammo completely until after you’re done reloading.
I know your talking about a glitch but I don’t recall ever seeing it 
Hmmm. The Sentinel Beam is a gun that can be stopped mid reload. In this case, I had less than 100 ammo left and none left to replace it, so I couldn’t reload. “100/0” on the HUD.
It’s a super minor glitch and I make it a point to carry forerunner guns as much as possible since I really like them. So it makes sense if I’m the only person to notice this.
It doesn’t refill the cindershot since it counts as a power weapon.
It’s not just hardlight, it can happen to any ammo type. As of this very moment I’m trying to fight The Harbinger and both Hardlight and Kinetic weren’t working for me (unfortunate as the Battle Rifle is very much a needed part of my arsenal because of it’s Anti-Skimmer/Skirmisher/Grunt uses) and the last time I had done the fight the Plasma Ammo wasn’t working either. I rary use shock weapons because I’m not a fan of the damage over time aspect (and also on legendary you need things that kill quick not slow) so it’s very much unfortunate that the ammo stations don’t work properly for me. The only thing I can say is that going to main menu and going back in fixes it (temporarily in my case) and it is very much an annoying bug
