Honestly, the tileset is pretty organized and was easy to use with the tilemap editor I have. But i'm pretty confident this sprite is missing in all of the color variants for Overworld:
This is from the Custom Minimap example image included in the pack, located at the top center-ish area.
This looks like (and I believe intended to be) tall grass or square bushes - either one works for what I'm looking to use it for. I can easily steal it off the example too but I was hoping to have all of the color variants.
Thanks again!
