On craft (base) screen, player have the option to add a new equipment to a slot that already has one. Game then start a replacement script, removing the previous one to install the new one.
Bug 1: When new weapon is installed, it is installed with no ammo of the apropriate type and sometimes keep the old ammo from the previous equipment (see screenshot).
Bug 2: selecting the ammo box (on right side, bottom of the screen) should list any ammo available on that base for that weapon so u can switch ammo types. Useful for shiva cannon and for when u forget to buy ammo before installing the weapon (or in case it runs out of it). Problem is that no ammo is listed on the left side of the screen so u can't selct and equip it. Code should be even more troublesome if ammo is a virtual one (like D-F tank for aerial laser), I guess.
