The bug

The planes composing dripleaf plants do not mirror on the back as one would expect, resulting in physical/illogical weirdness.

How to reproduce

1. Place a large dripleaf
2. View the light pixel on top of the dripleaf
3. View the leaf from below
4. Note that the position of the light pixel has shifted
