Free Halloween Tricks or Treats bundle???

I recently bought 2,800 San Van Bucks, and went to purchase the Tricks or Treats bundle, which costs 2,100 SV bucks, but didn't deduct 2,100 SV bucks from the 2,800 I purchased, and the game still gave me the Tricks or Tricks bundle. This is a VERY big bug. The screenshots are AFTER the purchase.
