On the Xbox 360 version the game freezes every time you hit a checkpoint if the total of weapons/weaponblueprints(not counting developer blueprints) in your workbench is over 30, it doesn't matter which as the total of both combines towards causing the glitch. I am not aware of if this happens on any of the other ports.
This glitch happened a little over a week ago when I had 15 custom blueprints and 15 crafted versions of the weapons in my safe, I fixed it temporarily by disassembling all the weapons in my safe and only keeping their blueprints. I assumed at the time that it was only the large number of weapons in my safe causing the problem and not the total of weapons and blueprints. From that point on I've been keeping only two weapons with me at a time and using my blueprints every time I swap weapons.
The glitch affected me again just yesterday as I hit 30 weapon blueprints. Currently if I wanted to craft anymore weapons I'd have to write down the exact parts and circuits for each of my weapons in a text file, delete all my blueprints, and refer to the text file every time I wanted to change weapons, which could be very annoying and demanding of patience to other players if I were to do so during a quick match.
I expected the game to have a less restricting weapon cap as weapon customization is one of its main selling points, and the main appeal of the game to me, I even purchased the Tau Volantis Survival Kit for the sole purpose of having more weapon customization options.
I really hope you guys can fix this as it is a very serious issue for me. I'll be keeping an eye on the patch notes, in the meantime I'll just hope someone doesn't crash the game by sharing a weapon blueprint with me, haha.
