Here are a few bugs i've found while simply being in Henesys being a henehoe: (they are no game breaking bugs or anything, just some tiny easy-to-fix ones)
Here are some other failed chair direction reversals:
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)
