Java Version: 11.0.14.1

Description

When you add a one shot launcher to your equipment list, it removes any ammo from any other weapon that is already on the build.

1. Add a LRM5 Launcher
2. Add LRM5 ammo
3. Add a SRM2 (OS)

Result:
LRM5 ammo is removed.

Doesn't seem to matter what ammo or OS launcher you use, seems to affect all that I tested.
