I've been away awhile, but is this feature gone now? What are we supposed to do with our seeds from Seedlings now?

The garden is still there

If you want to navigate there instead of linking there, there's barn and silo in the middle of the upper right of the map of Veta. It's almost directly above the cloud of balloons.

Thanks, both of you!

you are welcome!
