Warhammer 8th Edition Beastmen BSB Bug

**Describe the bug**
Under Warhammer 8th Edition version 9, the software is not flagging when someone places the, "Beast Banner" on their Wargor and then also places magic items on that character. You are only allowed one or the other, not both. You can replicate this with any magic banner while also adding any combination of magic items within the Wargor's allotted 50 points, ere go, a Wargor carrying the Beast Banner and then also, "legally" under your app, being allowed to also wear the Armor of Destiny.

**To Reproduce**
Steps to reproduce the behavior:
1. Open up the rules set for Warhammer Fantasy 8th Edition v9
2. Start a Beastmen army list
3. Add a Wargor to your army list and mark him as your BSB
4. Select the, "Beast Banner" as your magic standard
5. Select magic items within the 50 point limit of the Wargor

**Expected behavior**
If done correctly, you will see your Wargor BSB can not only carry a 75 point +1 strength banner, but also be given 50 points of magic items. The only error that will show, is that you have not spent your Core points limit.

**Additional context**
Just wanted to note that I had only come across this because a friend of mine wrote a Beastmen list on your app similar to what I have listed above and that was the first time your software caused a bit of an argument. haha I hope this has been helpful and I appreciate your time and efforts! Have a very merry Christmas! God bless!!

Start in the Beastmen Army Book data for Warhammer Fantasy 8th Edition v9 and reproduce the listed Wargor BSB setup in Battlescribe. Inspect how the Wargor, Beast Banner, and magic-item selections are represented; done means the combination is flagged as invalid while valid alternatives continue to work.
