I started Agrarian skies a while ago. While pretty much everything's working as advertised with the launcher (Even realized after a while that there was a separate map to load, duh), the one thing I can't get to work are fruit trees. Vanilla trees work fine, rubber trees work as well. But every tree from Pam's Harvestcraft simply won't grow.
I've looked through the ftb wiki, but there's no mention of any special treatment necessary. I tried growing one tree in creative, burning a stack of bonemeal. No result. Biomes were several, including magic forest and plains. Did I mess up somewhere?
The fruits aren't necessary for my survival, but I'd still like to grow them.
P.S.: Setup is a client/server. Used ftb launcher to download server and map. And using ftb launcher to launch client.
