Garden upgrade is not showing. I am playing from 0.17. I think garden was already upgraded in this.
If there is supposes to be a new garden upgrade in new version, it's not showing.
Unfortunately, nope. I went with the patch v18 as well, followed the readme - delete a handful of files, replace them and yet a few more with the files from the patch archive. Primary story parts of all the girls are triggered one after another, poor Lin is left untouched.
FOUND IT
You have to ENTER the garden to trigger a monologue, THEN the upgrade shows up with Ellen...
