You can currently only hold 999 of Light, Medium, Shotgun and Sniper Ammo, 30 Arrows, and only ~25 Rockets at a time. I’m proposing this change where I’d want a lower cap for grindy/survival PvE games, or if I want to increase the cap beyond 999 for PvE zombie/PvP modes, etc.
Note: In BR since v16.00, it’s only possible to hold 500 Light & Medium Ammo, 150 Shotgun Shells, 50 Sniper Bullets. This cap was not implemented into Creative (for good reason I suppose)
