The Bubbies have been updated to version 0.31. To update just take new boxes from the HUD and pack and unpack the bubbies with the new v0.31 box. And there is also a new Special Bubbie available at the main store, a Crystal Bubbie to celebrate the soon to be released Crystals, so go and pick one up.
The other part of the Bubbies ecosystem, the Orchs also need to be updated with a move to v0.31, this update will fix the seed problem as the Bubbies weren’t actually eating the seeds. Just pack and unpack your Orchs with v0.31 box which you can get from the HUD. If you have seeds, you must also do the same with seed cups.
