Weapon serial numbers do not repopulate after you purchase a weapon

[Developer-Bear]

Steps to reproduce:

1. Purchase a weapon from ammunation (note the serial number)
2. Observe that the serial number of the weapon in the shop does not update
3. Purchase a second weapon from ammunation

Result: Both weapons have the same serial number. (Can be done infinite times)

Notes:

• Closing and opening the shop repopulates the serial numbers (perhaps a short-term fix is force close the shop once a weapon is bought)
• You can purchase stacks of weapons (I assume because the serial numbers are the same?)
