I have noticed that the weapon ammo is being incorrectly capped at 50. If you enter a higher value...like 60, when you reopen the SF PC sheet, it will be set back to 50.
There should not be a cap at 50, especially since there are charged arms that go to 60, 80, 100, etc. Or, a user could be using Ammo to represent some other consumable quantity that exceeds 50.
