Hello, good morning. 
I spoke with the devs again.
There were two issues upon release of Unlocked & Loaded.
- Some Weapons May Show Their Max Stat Potential Incorrectly
On rare occasions when looking at a weapon card, the max potential stats distribution shown might not correspond to the actual values.
This will be usually signalled by a total potential stats value lower than 380.
The issue is only visual; the weapon card will update to the correct values once the first Empower operation is done on a weapon with incorrect values.
This issue was fixed with the latest hotfix 1.5.1.
- Incorrect Visual Rounding of Weapon Stats
On uncommon occasions when looking at a weapon card, the total value of the potential stats distribution shown might add up to 1% higher or lower than the maximum (380).
This is only a visual rounding issue, as the actual stats total will always effectively be 380 for every weapon.
This was initially believed to be a visual only issue. Now it’s been determined that it involves the backend delivering a value different than expected. The difference is small if it happens, but the rounding can make it appear larger.
You sending logs (and anyone else experiencing it) helps a lot with us being able to diagnose the exact issue.
I’m going to be updating the known issues area of the hotfix to reflect this.
