Some items, most notably bowls of nectar, have a copy of the item model near them in inventory, in item frames, as dropped items, etc. The copy seems to be shifted by a few pixels to the upper left corner and a bit backwards (it appears to be behind the item frame).
This occurs only when Geckolib is installed. Without it, the items render correctly.
Affected items include: all bowls of nectar and custom flower, custom mushroom, custom mushroom block in the item form (not placed).

Do me a favour and test this again after the next update

Fixed, thank you!
