Potential bug:
Most of these I found in two minutes while sitting on chairs I had on me, there's hundreds of more out there too, feel free to reply with other unimportant bugs if you want, it's kinda funny to find these kind of bugs, who knows, maybe they'll be swatted with Nexon's fly swatter.
(might update with more later)

Choco-buff-neutralizer incorrectly states in the description in Cash Shop that it will allow you to consume 80 chocos without Choco Frenzy, once used it states it can only do 50
