Where it is sensible, this has been handled. Yet there are still cases in which a character has items displayed that they can not equip according to the rules. This is mostly the case for the generic magic items and factions that can't equip the mundane version of the item. For example, Ogres have generic magic shields listed among their options but can't equip a shield. Another example, Wood Elves have magical plate armor listed but can't equip mundane plate armor. A final example is that Organ Guns have all runes listed but can't take some of them. This can't be changed efficiently. You just have to know your army and be aware of what you can equip and what you can't.

If you want Battlescribe to calculate your allowed percentage of allowances, you need to set a point limit. By default each list has a -1 point limit, which means you can do whatever you want. You have to set a point limit for your game for the allowances to be calculated.

Do not put multiple forces into one roster. If you do, BS will calculate the allowances for the whole roster instead of calculating it for each army separately. If you want to make a list using the allied rules, make separate rosters for each army.

Updates are not regularly scheduled. Maybe once a month, once a week, depends on how big the updates are and at the convenience of the data editors.
