Franz doesn't understand my transaction.

Repro-steps :
1. Enter the Ironheart Armory, manned by Bastian Ironheart.

2. Bastian being entirely focused on his work, pick up a set of armor in the shop.

3. Observe the armor is added to my inventory.

4. Manage to attract Bastian’s attention to pay him.

5. Complete the transaction.

6. Notice Franz adds a second Leather armor to my inventory.

7. Correct Franz out of character about the extra armor.

8. Notice that Franz agrees, but that in his correction of the game state he simultaneously adds and removes a leather armor, effectively doing nothing.
