BUG - Items Undo option defect

CONTEXT

• I was with Lucian doing a bot game for FWOTD
• Recalled with very low HP
• Immediately bought items (i think it was boots and a potion)

DEFECT:

• After I bought the items I thought "i think I won't be needing the potion"
• I click the "Undo" buttom in the items store
• Immediately after I click it, my HP and Mana bars get reduced to the values of when I bought the items

DEFECT REPRODUCTION:

• returned with low (ie: 5%) HP to base.
• buy items at 50% HP (because of regen)
• wait for HP to reach 100% (without closing the item store - did not test otherwise)
• click "Undo" in the items store
• Gold was returned AND health was reduced to 50% (HP at time of buy)

Why is the model's status being updated all together? Shouldn't just the inventory and gold properties be updated?

Regards
