Last Moa can't be sold, Moas can't be claimed with one slot

[Athgaar]

Two Moa bugs:

One, if the player has exactly one Moa in inventory, it can't be sold; the error message is "Cannot sell items; you must keep at least one of every weapon category" as if it were the player's only primary, secondary, or melee weapon.

Two, if the player has exactly one robotics inventory slot, trying to build a Moa prompts the player to buy more robotics inventory slots; I suspect that leftover code from sentinels (which come with weapons) is incorrectly being used to make sure that both the Moa and its weapon (which it doesn't have) have space to be accepted.
